DIY gold trap lazy person. Types of equipment for gold mining

Gold has been a measure of wealth since ancient times. Its production has long taken the form of an active form of income, although it is not an easy task. Precious metal is not so often found in nature compared to other useful substances. A dredge for gold mining can significantly improve the efficiency of complex work. However, it is important to remember that at present individual entrepreneurs and individuals do not have a legal basis to search for precious metal. The volume of illegally mined gold is approximately 10 tons - 10% of the annual production of all of Russia.

How to make a sluice for gold washing with your own hands. Part 1.

This article was born in connection with the increased interest in gold mining.
I often get asked questions about how to get gold from streams and rivers? How to make a gateway for gold mining with your own hands? Where and what kind of gateway should I buy? How to make a passage with your own hands? In this article I will tell you how to make a gateway with your own hands. The equipment is so simple that anyone can make it in a couple of hours at home and in many respects it will be better than a purchased American aluminum gateway, the cost of which in Russia reaches 17,000 rubles.

I’ll tell you how to properly make a gold-catching sluice, a mini device for gold mining, popularly called a prodnushka. This is what the prospectors of Siberia and the Urals call it, the name that came to us from our grandfathers and great-grandfathers is prodnushka.

A passage (sluice) is a box made of three boards, at the bottom of which a mat is laid and a stencil (riffle) is placed. A walk-through made of wood is not only simpler and cheaper than one made of aluminum, but most importantly, if something happens, you won’t mind throwing it away. If you use dry and not thick wood, then the weight will be no more than that of an aluminum analogue, and with a skillful approach, even less. In addition, wooden boards in your car or backpack will not raise questions from strangers; no one will ask what kind of boards they are or ask unnecessary questions. You never know what purpose you need these boards for in the forest.

To make a passage (sluice) for gold mining, the main thing is to follow the basic simple rules in its manufacture, and you will be a more successful gold miner than other prospectors with short purchased sluices.

Gateway length.

The longer the hole, the more gold you will catch. Foreign aluminum sluices have a maximum length of 1.5 meters; this is not enough to catch fine gold and disintegrate poorly washed sands or loams. The length of foreign locks is 1.5 meters due to legislation that limits the length of the lock, so that amateur tourists do not wash out all the gold on the stream and leave it to others. For example, in America, Australia, and New Zealand, gold mining is a hobby, like picking mushrooms or fishing in our country.

The width of the sluice depends on the amount of rock supplied; for bucket feeding, a width of 20-25 cm is sufficient.

To make a long and easy-to-carry passage, use a cascade of gateways, for example, install two gateways of 1.5 meters in series, for a total of 3 meters. This is sufficient to trap fine gold and disintegrate the rock.

If the soil is clayey and does not have time to be washed through the passage, you need to use other equipment called butara. I will talk about it in the following articles or videos on my channel https://www.youtube.com/user/RudolfKavchik

Installation of riffles or as they are also called stencils.

The stencil is the most important part of the pass-through. Behind them, a turbulence of the water flow and its rarefaction occurs. This creates conditions for the accumulation of the heavy fraction behind the riffle plates and the demolition of light unnecessary material. The angle of inclination of the riffle plates depends on the amount of water supplied to the passage and can be from 45 to 78 degrees. The greater the depth of the flow and the speed of the flow of water supplied to the sluice, the greater the angle of inclination of the riffles. The distance between the riffles is 5-7 cm. The shape of the riffles can be straight or with slightly curved edges in the direction of flow.

If the water flow is weak, then riffles are not used. The rock is sifted through a sieve before being fed to the mini device. See the chapter on material screening below.

Gold catching mat.

A gold catching mat can be made from any natural fabric, such as burlap, tarpaulin, and even an ordinary waffle towel that housewives use in the kitchen will do. The main purpose of the mat is to ensure that the riffles adhere to the bottom of the sluice so that the accumulated material is not washed away by the leaking flow under the riffles.

Industrial enterprises use cellular gold-collecting mats. This is due to the technological process of gold mining. The rock is transported to the industrial equipment by multi-ton Belaz trucks, washing thousands of cubic meters of gold-bearing rock per day. Each Belaz truck contains ten grams of gold, which is brought in for washing every few minutes. It is not profitable for the enterprise to stop the washing process to unload the industrial equipment; this will require stopping production for 2-3 hours, and time is gold, in the literal sense of the word. The industrial device is unloaded once a day. Due to the large amount of washed rock, there was a need for cellular mats with a high profile, which accumulate heavy metal and prevent it from being carried away by the flow of water, which increases the time of effective operation of the industrial device.

At its core, a honeycomb mat works like a stencil/reel. In the depths of the cells, vortex flows are created that carry away light particles of sand, leaving heavy metals at the bottom: gold, platinum.

You don’t have to use a cellular mat in the passageway, since the rock for washing is not supplied by dump trucks, and gold can be easily removed at any time as heavy material accumulates. In addition, a cellular mining mat is not easy to obtain and its cost of several thousand rubles is not at all justified when used on mini devices.

You can make an analogue of a cellular mat yourself from an ordinary household cellular mat, which many people have on their porch and is sold in every hardware store under the name “anti-slip coating.” The mesh size of the anti-slip coating is approximately 5 mm. See photo.

The anti-slip coating is laid on top of the rag mat. Ribbons are installed on top. Such a system will work no worse than an industrial rug, it’s easier to buy, and its cost is much lower, and if something happens, you won’t mind throwing it away.

How to make a gateway for gold mining with your own hands. To avoid buying.

Video on how to use the pass-through. Also, you will learn what raft, peat and gold-bearing rock are - sand or layer.

Where can a future prospector find information?

The Internet is a source of much knowledge that can be perceived by a person in any corner of the globe. In this regard, gaining knowledge in the field of gold mining at home is a very real prospect. Washing gold by hand was captured on video by many users of social networks and other portals. As a rule, this is a video filmed directly at the mining site.

Water is drawn into the tray along with sand, after oscillatory movements it splashes out, leaving a certain sediment in the recessed central part. The sluice is installed directly along the stream. Here visibility is minimal, but this corresponds to the small scope of the miner's activities. It is important to be able to distinguish potentially gold grains from sediment of other metals and ordinary sand. The panning device can be used for gold mining on an industrial scale. You can purchase such a machine in specialized stores; the most convenient way to do this is on the Internet.

Here you can compare the parameters of different models, evaluate engine capacity, power, structural strength, a set of additional functions, total weight, and prices. A detailed study of the assortment will allow you to learn more about the industry itself and choose a good option to start with. An industrial device for gold mining can be rented, like any large-sized equipment.

Gold has captivated the imagination for centuries. Washing on trays gathers its audience on video sites. The opportunity to try your luck on a river or mine is provided as a tourist option. Many people go camping to find their happiness by sifting through soil and sand. Someone uses a metal detector, looking for placers.

In the summer, the extraction of grains is easier, especially in central Russia, in Altai. Where there are areas of permafrost, this method of extraction is not possible. This activity does not always require specialized education; often, people who are far from cartography and geodesy are involved in the development. Luck plays a big role, because it happened that people not only panned a few grams of gold, but also found nuggets - large pieces of gold. Its cost depends on the purity of the rock; it is not for nothing that every ingot has its own hallmark marking. Gold is a finite resource, so if you dreamed of finding your ingot, or even a grain of the yellow metal, hurry up.

We also add that the Golden-Inform portal can advise you to purchase a portable manual washing mini-sluice for gold exploration and mining from our partners from Cybermash LLC, whose contacts are attached below:

One of the options. Easy to manufacture. Moisture-resistant plywood is taken. Or any other plane. Chipboard can be moisture-resistant, but it is rough and when removing gold, it will cling to all the irregularities. You can paint and even putty. Lay down a piece of linoleum. Whatever is at hand. A rubber drag carpet No. 362 is laid on top. It is sold in dimensions of 1000 mm by 800 mm. Cut in half. We get two pieces 500 mm by 800 mm. We put them one after another. We press it from the sides with baseboards. Or like on my scout there are slats on the sides and spacers. Be sure to fix the joint with something, otherwise the second carpet may lift up during work.

Gateway for gold washing. Make your own equipment for gold mining.

:

Hello, do you have a washing tray for sale? Thank you, Alexander.

Alexander. Under the advertisement for Sale of Prospector's Tray there is the seller's phone number. Call him. I personally don't sell trays. I can make a gateway, but I can make any of the ready-made materials myself according to the description. Happy searching.

How can I contact you? Can I leave an email or phone number? I want to order a gateway)

My email is in the right column. [email protected]

How to contact you

Vladimir I can’t find your email, I wanted to consult with you

You can ask a question in the comments. I just won't publish it. I will answer your email. Or above your comment is my name. Click

how to make a simple concentrator at home to catch the smallest metal particles

Have you found a way to wash small gold? I can give you some advice.

Could you describe your method? Readers would appreciate it. My mail

How can I contact you about the gateway?

My mail

Near the house in a ravine I tried to wash a lot of pink stones, apparently rose quartz, the shape of the stones has sharp corners, scratches the glass but does not wash off. Then I washed the area and there were also these pebbles, but smaller. Interested in the riffle angle

I can't always respond to comments quickly. I'm sorry. The angle of inclination is not important if taken separately from other factors. What metal? Small? Large? How much silt is in the water? What current? All these are components of success. Only personal experience will dot all the “Is”. After the tenth and twentieth wash, you will understand what you need. After all, I showed the simplest design that can be improved. In the near future I will publish material on how to make a simple concentrator at home to catch the smallest metal particles. The concentrator can also be used while traveling.

Types of equipment for gold mining

To extract gold, people have come up with many devices that make working in mines easier. True, mining the precious metal with your own hands is prohibited in Russia today. This can only be done by companies that have received the appropriate license. Therefore, private miners are mainly limited to rivers, which carry small particles of material in their waters. As a result, washing equipment for gold mining has become most widespread.

Gold mining: equipment

Industrial gold mining is carried out using dredges. This is a bulky unit weighing several tons and the size of a four-story building. The device is equipped with a mechanism with scoops that lifts soil from the bottom of the reservoir. Next, it goes through several stages of washing, as a result of which the metal is separated from the soil and deposited at the bottom of the trays. The advantage of using a dredge is that all stages of gold mining are concentrated on it. A relative disadvantage is that the unit cannot operate without water.

There are two types of industrial dredges:

In both cases, due to the cost, only large mining companies with a state-owned scale of activity will be able to afford to purchase such equipment. For small cooperatives and individual entrepreneurs, mini dredges are more suitable, the prices of which are several orders of magnitude lower.

Types of equipment

Depending on the purpose, the tasks assigned to the miners and other goals, the equipment is divided into several types. All of them are collected in the table below.

Is it possible to make a dredge with your own hands?

Based on what was written above, it is theoretically possible to make a mini dredge, but you will have to buy some additional parts. In any case, it will be much cheaper than purchasing a new device (about 3 times). However, it is not a fact that a device assembled by yourself will work well. When designing, you need to take into account many nuances.

Required tools, materials and components

Self-production only involves assembling all the mechanisms into one whole, since it is almost impossible to construct them with your own hands. The list of what you will have to buy consists of the following units.

• Motor - it will turn the main elements.
• Pump - a centrifugal water pump is suitable.
• Compressor - needed to produce air for breathing underwater.
• Pipes are a readily available material.

I would like to draw your attention to the fact that the pump and compressor must be attached to the motor and use its energy to function. Therefore, when purchasing, you need to ensure that their installation is as simple as possible.

You can also buy a gateway, but it’s quite possible to make it yourself. To do this, you will need aluminum profiles, galvanization and metal of various shapes.

General form

Conventionally, mini dredges are divided into portable and stationary (more productive). The latter are considered more cost-effective because they can operate in deeper bodies of water and are equipped with a compressor to generate air so that the miner can remain under water for a long time. General diagrams and drawings of such installations are presented below.

In addition to these, there are also so-called hand dredges, which are convenient to work with in shallow water or in streams. The principle of operation is the same, only all the equipment is attached very compactly, which allows you to carry it in your hands. The unit itself is somewhat reminiscent of a vacuum cleaner for gold.

The simplest devices

Several approaches are used to extract gold:

• manual;
• hydraulic;
• using dredge;
• ore method.

The latter approach requires, during production, the presence of expensive industrial equipment. Private miners use three other methods.

The simplest equipment for manual gold mining is a regular tray.

Working with it is based on the difference in the weight of the fossil material. To get gold with your own hands, you need to scoop up sand along with water with a tray and place it under the current. If metal particles are present in the collected material, they will settle to the bottom.

This washing device is quite popular among novice miners due to the fact that it:

• does not require large investments (its price varies between 500–2000 rubles);
• allows gold mining at any time of the year;
• characterized by increased mobility.

The main disadvantage of such a washing device is that it does not allow the extraction of a large volume of precious metal. In addition, before using the tray, it is necessary to conduct a large-scale geological exploration of the area.

The so-called lazy person allows you to speed up the process. It is a kind of gold trap, which is often used during heavy floods. It is recommended to install the “Lazy Man” on rivers adjacent to gold deposits.

The tool itself resembles one of the sections of a mini-dredge. The height of its walls reaches only 5–6 cm, while their thickness should not be less than 8–9 mm. The latter is due to the fact that the mining tool experiences serious loads over a long period of time.

The mini-dredge also includes:

1. Inlet and outlet openings, which are partially closed by small thresholds.
2. A special mat - it spreads at the bottom of the deck, and rock particles settle on it.
3. Claws with holes that are attached to the bottom of the trap, they are necessary to hold the gold mining device in one place.

The simplest devices are used by novice miners. They do not allow you to collect a lot of gold, however, they provide the opportunity to learn how to search for and mine precious material.

Structure of a compact device

Mini dredge design drawing includes:

• a floating platform similar to a catamaran;
• motor;
• hoses;
• compressor;
• pump;
• gutter

The frame of the device is often made of lightweight materials, for example, aluminum. Car tires or plastic structures, for example, 40-liter barrels, are used as a platform. The gutter can also be made from steel yourself.

Often the scheme of its structure is based on the “Hungarian effect”, when the incoming liquid forms a waterfall due to the sills arranged. This allows it to not foam too much and preserve metal elements. Parts of the gutter are welded into a lattice and secured to an aluminum sheet - a gateway, which has a specially curved shape.

Important! The elements are laid with “miner’s moss”, which looks like spaghetti. This design is capable of retaining gold particles.

It is noted that the preferred hose diameter is 10-12 cm. A larger size causes significant physical stress. It’s rare that anyone can withstand it when doing the work independently. The mini-dredge for gold mining is assembled in such a way that water along with the soil enters the sluice head through the socket. It is necessary to ensure a water supply without sand - a special valve is installed for this.

The presence of small grains of sand will damage the pump.

Industrial device

More experienced miners prefer an industrial device for gold mining. This device has a number of valuable advantages, including:

• ease of use;
• increased reliability;
• relatively high productivity;
• maintainability.

Professional geologists take part in the development of industrial devices. The result is a tool that takes into account the specifics of gold mining and the needs of miners. Today on the market you can find industrial devices designed for personal, group and industrial mining of rock layers.

Structurally, such equipment consists of:

• an engine running on diesel fuel, gasoline, electricity;
• battery;
• gearbox;
• a bunker into which the rock is supplied;
• drive units;
• a drum responsible for irrigation and rock crushing;
• enrichment gate;
• stencil.

The last element, in fact, is the main component of the industrial device. Gold settles on the stencil.

The process of extracting precious metal using an industrial device is as follows:

1. Soil is loaded into the receiving hole, which could potentially contain gold particles.
2. The machine washes the loaded soil, clearing it of excess fractions. Modern devices are complemented by the function of flushing large rocks.
3. Next, the soil is fed to a drum, which irrigates and crushes it into small pieces.
4. At the penultimate stage, the soil enters the enrichment sluice.
5. At the end, the remains of the extracted material are thrown back.

Each industrial device allows you to configure:

• fuel consumption rate;
• intensity of material cleaning;
• drum power;
• cleaning method depending on the type of soil.

There are also dismountable models of industrial devices. They are capable of processing a relatively large volume of rock. This equipment has long been highly popular among private gold miners.

Dredge device

If we talk about a dredge with a bucket working element, then there is nothing complicated in its design. However, there is also a vacuum type of installation, the design of which is different in many respects. It is intended for bulk deposits, which include marine gold-bearing sands. The machine consists of the following mechanisms.

• Pump - creates a suction effect.
• Sleeve - passes rock through itself under the influence of a created vacuum.
• Auxiliary hose - connected to a pump that pumps water, and directs it through a high-pressure pipeline into the hose.
• A sluice is a kind of container that calibrates the rock and throws away large debris.
• Butara - acts as a flushing mechanism.

All these elements work harmoniously, that is, together. Most often they are installed on a floating gold mining platform that operates on water. They are rarely used in quarries.

Draghi

In essence, a dredge is an improved version of an industrial device. Its basis is:

• engine;
• water pump;
• air compressor;
• hose;
• suction device;
• water collection pump;
• a bell that acts as a water collector;
• ore washing sluice.

The total weight of the dredge varies depending on the model. When this device operates, the hose is lowered into the water. Through it, soil collected from the river bottom enters the ore washing sluice, due to the operation of the engine. Next, the drum and other structural elements of the dredge come into play.

This equipment is often supplemented with a pump. This organization allows the manufacturer to collect soil anywhere in the river without being tied to the bank. A mandatory element of the dredge design is a pressure hose. It is connected to the engine and is responsible for sucking in gold-bearing sand.

The table shows an example of the capabilities of one of the drag models.

Basically, such equipment is capable of lifting soil located at a depth of up to three meters.

Dredges are the optimal device for collecting precious metal. They work more efficiently than industrial devices and greatly facilitate the work of the miner.

What is a dredge?

Dredges are special machines designed to work with different types of soil. The main functioning element of such installations can be either a multi-bucket in-line mechanism or a suction hose (if the rock is loose). The scooping mechanism is adjusted by a staff of 10 people.

Simply put, this unit acts as an attachment that can be installed on a floating platform or ground transport, and is somewhat reminiscent of a conveyor. Only instead of a tape, movable scooping devices are attached to the frame. They are the ones who scoop out gold-bearing ore from a quarry or from the bottom of seas, oceans, rivers, etc. Subsequently, the extracted conglomerate containing the required element is transported for processing. Below is a photo of the car itself.

Metal detectors

Metal detectors are used in cases where miners do not want to pan for gold. These devices make it possible to find deposits of precious material underground.

Modern metal detectors are highly sensitive. They can discover deposits of 1 gram of ore hidden under several kilograms of rock.

Such equipment operates on the electromagnetic principle. At the end of metal detectors there is an antenna shaped like a ring or an ellipse. It generates electromagnetic waves, which, when in contact with metal, cause a response. As a result, the device detects the presence of deposits of a certain ore in the ground, emitting a characteristic signal.

The main disadvantage of a metal detector is that it detects any metal deposits. Expensive devices of this type are equipped with an additional microcomputer, which, based on the data received, is able to determine the type of material located in the ground. The use of such equipment allows you to avoid processing soil that does not contain gold masses.

Metal detectors differ from each other in the following parameters:

1. Search depth. This parameter depends on many factors: antenna power and size, signal frequency, soil characteristics. High-frequency devices are capable of capturing metal particles up to 3–5 mm in size. Moreover, such metal detectors can detect material lying almost at the very surface.
2. Sensitivity limit. The detection limit refers to the minimum particle size that a metal detector can detect. In cases where the nugget has a diameter less than the specified limit, the device will not be able to detect it, regardless of the depth of occurrence. The sensitivity indicator directly depends on the frequency at which the device operates.
3. Ability to recognize material. To recognize metal, modern detectors are equipped with a discriminator. This device allows you to determine the type of deposit without excavation. However, it is important to understand that discriminators do not always accurately identify gold nuggets. Even with such a device, metal detectors often give a false signal.

Inexpensive metal detector models

Among the inexpensive models of metal detectors that allow you to detect deposits of precious metals with fairly high accuracy, the following can be distinguished:

1. White's Goldmaster-3. This device is capable of detecting nuggets measuring 3–4 mm. Goldmaster-3 is complemented by a discriminator, which relatively rarely gives false signals.
2. White's Spectrum XLT. Spectrum is used to search for any metals. It is equipped with a display on which various information is displayed. Using this monitor, you can reprogram the metal detector for specific tasks. In the initial version, the device offers 5 built-in settings: searching for coins, conducting geological exploration and more. In addition, Spectrum provides a semi-automatic soil balancing function, the presence of which speeds up the search.
3. Fisher GoldBug. This metal detector is one of the most affordable on the market. It can detect deposits of precious metals whose size does not exceed 3–4 mm. However, the device is not equipped with a discriminator, and therefore the soil has to be processed regularly. In the GoldBug2 model this drawback is eliminated.

Blower

A blower, or pneumatic sluice, is used in those gold-bearing areas where there is no access to water. The device is mainly manufactured using the “handicraft” method, and can process up to 1.5 cubic meters per day. m. sand.

The blower has several stencils on which the gold is deposited. Sand is fed manually onto a perforated belt installed at a certain angle to the ground. The ore rock rolls down along it, and particles of precious metal penetrate into the bunker located below.

Today, blowers have begun to be equipped with a small gasoline engine, which allows partial automation of the gold collection process.

Equipment designed for the extraction of precious metals is divided into several types, each of which corresponds to the purposes for which such devices are used. They allow automatic and semi-automatic processing of gold-bearing soil.

Operating principle of the dredge

Dredge equipment, regardless of whether it is a pump or a bucket, is designed for one purpose - the extraction of ore containing valuable minerals and its transportation to the destination, that is, to the place where the mined material is either processed or immediately washed (as in the case with gold).

For example, a bucket dredge most often simply dumps the mined conglomerate into a heap, but a floating pumping station immediately washes and collects pure gold, throwing unnecessary debris to the bottom. But the principle is the same - extract, transport and sift.

Do-it-yourself gold washing tray: manufacturing rules

Gold mining is often compared to fishing. People have been improving ways of mining solar metal for many years, hoping that they could become richer. Gold panning is considered the most ancient method for extracting the precious metal.

Today, this procedure is carried out using industrial methods, but the washing tray symbolizes miners from all over the world. Using trays you can mine not only gold, but also diamonds and other precious metals.

For on-site testing, a gateway with a width of 25-30 cm and a length of up to 1.5 meters is suitable. It is a rectangular path along which the river current drives sand and silt.

Details of the miner's craft

If you dream of getting your piece of gold, all you need to do is make a plan so that you can make your dream come true. Gold is found in the depths of the earth. It is often found in sand, which is brought from mountain streams, and is also present in compounds with other fossils, such as quartz. There are many mined-out deposits on the territory of Russia, where, however, remains of gold ore can be found. Along with this, you can explore gold-bearing streams. It is believed that the best results can be obtained in rivers whose length does not exceed 15 km. In this case, we can talk about a placer of gold. Nuggets weighing more than 30 grams can also be found, but they are hidden at the bottom of the river, under a layer of silt, 10 to 30 cm deep.

The success of mining gold with your own hands depends on:

• Well-chosen site;
• Modern equipment;
• Low costs for carrying out work;
• Climate.

How to make a gold pan?

Many people are interested in how to make their own gold pan. The simplest thing is to buy a plastic basin in a store. But this option is suitable only at first. You will need a spatula for the tray, which is designed to collect the concentrate and analyze it at home comfortably.

Expanded mesh

You can easily make your own washable tray yourself. This will require construction materials. You can easily buy them at the market or in construction stores. To create a frame, a metal tray is suitable.

If this is your first time creating a tray, make a small model so that you can create a full-size version later without making any rookie mistakes.

Materials required to create a wash tray:

• connection in the shape of the letter "T";
• expanded mesh.

The mesh must be fastened to a metal sheet. The T-shaped connection is secured to the area that will stand on the ground.

How to make a washing tray out of wood?

A washable tray made of wood is popular among gold miners. Even a novice miner can make it with his own hands. It is best to choose blanks from dried pine or aspen to produce a glued laminated tray.

When making it, you should follow the following recommendations:

1. Prepare two planes and two sides separately. The first and second blanks (bottom) should be cut from a solid log, cutting at an angle of 45%. Using this method, tree rings make the tray more catchable.
2. All 4 parts of the washing tray should be carefully planed and fitted to each other. Carefully monitor the accuracy of the sides and their symmetry. They should mirror each other so that the tray has the correct symmetrical shape.
3. Glue the first and second planes to the board with glue and screws. Make sure that the joints of both planes are tight and durable. To do this, connect them in a groove with glue.
4. The ends of the boards that protrude beyond the end of the side must be cut down, leveled and rounded. An eyelet is drilled on board to attach the tray during camping trips.
5. If you find any cracks on the mining tray, they should be covered with a mixture of glue and sawdust. You should not paint the tray, because the paint will remove the wood structure and the catchability will become poor. Also, do not burn the surface, as this will add pits to the surface, which will reduce the quality of the tray. The black color produced by firing can mask concentrates that the miner must quickly detect.

The finished washing tray will have light weight and high strength, obtained by perpendicular layering of the tray parts to each other. This protects homemade equipment from splits, thereby increasing its quality.

If you leave a steeper angle between the planes, this will be disadvantageous due to the dead space formed at the joint. This part of the tray will constantly become clogged with silt. High sides can lead to a similar problem.

Using these recommendations, you can make a washing tray with your own hands. There is a legend that panning for gold from self-made tools will bring good luck to its owner throughout the entire mining period.
