Cost calculation

What it is

It is impossible to find a pure element in nature: in any case, it contains impurities. To make jewelry, it must be cleaned, but the share of pure metal in the finished product does not exceed 75%.

Gold that has been purified from impurities is used only for investment purposes. It is also used as sputtering in electronics. And in common people it is also called “technical”. It is not suitable for making jewelry, but is widely used in other fields.

Rules for buying gold

Products can be purchased by adult citizens with an identification document.

Technical procedures, such as clarification of the name, weighing, determination of the sample, analysis using chemical reagents, as well as detection of cuts in the product are carried out in the presence of the seller. The owner independently inserts minerals that have any significant value.

Jewelry and scrap are sold for purchase if they have the appropriate purity, from the lowest 375 to the highest 999. The cost of a gram of metal will be higher, the higher the purity. Weighing accuracy is 0.01 grams. When buying, the presence of a mark - a manufacturer's name or hallmark - is not taken into account. At the same time, if the seller does not have documents for the right to own commemorative personalized or anniversary medals, such items will not be accepted for purchase.

Areas of application

I have already said that such an alloy is used in various fields:

1. Most of this metal is used in electronics. After processing, the gold ends up in radio components.
2. In dentistry it is used for the manufacture of dentures.
3. Cancer and tuberculosis are treated with the help of individual isotopes of gold.
4. Component of some medications.
5. Some parts in the aviation industry can only be plated with gold.
6. Gilding metals protects them from corrosion.

How is it mined?

10% of all gold mining is used in industrial devices. It turns out that the metal can be extracted from there. This process is called refining. It includes cleaning the alloy from all impurities.

What technology is there?

As I said, the gold is in the technical details. A mobile phone, laptop, printer, scanner and other common devices are a source of small amounts of precious metal.

Costs of separating gold from radio components

In production, when using special equipment, they justify themselves, although refining is not an easy process. Some craftsmen are trying to mine gold at home. In this case, you need to make sure that the end result covers the costs, because you will have to purchase a lot:

• dishes for melting;
• stirring stick;
• funnel;
• high temperature stove;
• porcelain containers;
• various reagents;
• protective equipment (gloves, etc.).

Extraction technique and purification of impurities

Refining is carried out in different ways:

1. Chemical. Its essence is the dissolution of metal in aqua regia. Before carrying out work, find out the amount of silver, if it is one of the impurities, since silver will not dissolve. Aqua regia is prepared from nitric and hydrochloric acids. The solution must be used immediately, otherwise it will lose its properties.
2. Dry. Tin chloride is used. It must be mixed with hydrochloric acid and water. Once the reaction is complete, the gold can be melted down.
3. Electrolysis. It will require a 999 sample. It will be the anode, and gold will settle on the cathode. You also need a bath filled with a solution of gold chloride and hydrochloric acid, where electrolysis will take place.

There is an interesting technique for obtaining technical gold from radio components:

1. Use a magnet to remove gold-plated steel.
2. Immerse the part in a solution of hydrochloric acid and peroxide for a week.
3. The exfoliated flakes are washed using a filter and fused.

We buy Autocatalysts

Autocatalysts

The catalytic converter (catalyst) is one of the most important components of a vehicle's exhaust system. It is designed to ensure compliance with standards for the volume of emissions of harmful substances into the environment. You can often find information on the Internet, from which it follows that precious metals can be extracted in small quantities from one extracted component. However, is this possible to do in practice?

Part design

The catalytic converter contains a structure made of ceramic or metal and consisting of a larger number of honeycombs. Their surface is additionally covered with a layer of metal of small thickness.

The internal design of the component provides an increase in the surface area that comes into contact with the exhaust gases. There is a special catalytic layer on it. Thanks to its presence, the necessary chemical reactions occur. They help transform exhaust gases into environmentally friendly ones.

The honeycomb of the mechanism is coated with an alloy containing precious metals. To create it, platinum, palladium and rhodium are used, which have a high cost. Their price can be two or more times higher.

In addition to the listed materials, modern cars produced in Germany and the UK include catalysts containing iridium.

Vehicles made in Japan and China have 15% less platinum in their catalytic converters than European brands. Domestic cars contain 40% less rhodium than their European counterparts. American-made car catalysts contain 50% less precious metals than those made in Europe.

Our company has been purchasing catalysts and is ready to offer favorable conditions for cooperation.

Waste enrichment methods

The extraction of precious metals and automotive components is carried out using hydrometallurgical and pyrometallurgical methods.

The raw material for processing contains a large volume of ceramics, as well as a small concentration of noble metals.

When processing components of radio electronics, scrap is used, which, in addition to valuable elements, contains plastic particles.

In the process of recycling automobile mechanical waste, the main task is to extract precious metals that can be used for subsequent secondary processing.

The hydrometallurgical method of extracting precious metals in a catalyst is used in compliance with the following sequence of actions:

• leaching of foreign materials using mixtures of acids, the composition of which is determined depending on the characteristics of the noble metals contained, which is carried out at temperatures exceeding 100 C;
• acid-insoluble material is washed repeatedly with water;
• At a temperature of 200 C, the semi-finished product is dried, and at a temperature of about 600 C, calcination is carried out.

How is palladium mined?

Palladium is extracted using other methods, which makes it possible to rid the material of foreign impurities that can reduce the cost of the material.

The most notable is the galvanic method or electric arc heating. In most cases, extraction is accomplished by heating the catalyst to a temperature of about 500 C, and then fluoridation is performed. The choice of this technique ensures the extraction of almost pure palladium, in which fluorine is present in a small volume.

The next stage of processing the material consists of cleaning it with mineral acid after it has cooled to 100 C. The procedure ensures that the metal is cleaned of fluorine and free of impurities.

Content of precious metals in different types of catalysts

Catalysts are purchased at a fairly high price . The metals used are rare earth. Their production volumes decrease annually, and their exploitation as secondary raw materials is relevant only on an industrial scale. From one catalytic converter it is possible to extract 0.05-0.1 grams of noble metals, which is possible when using 50 grams of various reagents. The volume of the latter can be reduced only in the case of working with a large amount of source materials and using cumulative extraction methods. Precious metals are extracted from the following types of catalysts:

• Automotive. They contain two groups of alloys: palladium in combination with iridium or palladium with rhodium.
• Industrial. Catalytic converters of this type can include complexes of several components: palladium, rhodium and platinum, as well as a pure monometal. In some types, silver can be used as a catalytic reagent.
• Industrial catalysts used for oil refining. They will include combinations of nickel with molybdenum or platinum with aluminum oxide.

Conducting a preliminary cost assessment and receiving materials

Acceptance of secondary raw materials is carried out by specialized companies, which mainly enter into cooperation with processing enterprises. Catalyst evaluation is carried out using the following equipment:

• spectrometer - a device designed to determine the chemical composition based on spectral analysis;
• scales with high measurement accuracy;
• tables for determining prices based on product labeling.

The price of precious materials is determined by the London Stock Exchange and exchange rates. The data from the table is used as a basis for calculations after obtaining the results of the analysis on the percentage of noble metals. Secondary analysis is performed after grinding the ceramic honeycomb, which allows us to obtain the average element content. Depending on the values, the blowing cost will be determined. The products differ in the following parameters:

• type;
• model;
• mileage;
• terms of Use.

Old catalysts installed in Soviet-made cars are readily bought up, since they contain an increased content of valuable elements.

We purchase used catalysts and radio components at high prices and are ready to advise anyone on relevant issues.

Where can you buy and sell

If you go to a regular pawnshop, nothing will work. There are special points for the purchase and processing of technical gold. Each facility must have a license to operate.

Price per 1 gram

The price varies from organization to organization and depends on:

• amount of metal mined;
• demand for it;
• exchange rates;
• distribution of the country's gold reserves.

Below is the price for today for Russia according to the Central Bank.

But if you managed to isolate technical gold, then you won’t be able to sell it except at the “scrap” price.

Who buys gold?

When selling gold or gold-plated items, you need to follow simple rules and know who to sell to. >In banks you can get absolutely accurate indicators of the weight, uniqueness and price of a gold product. With competent legal support, the cost of a product acquires the most accurate estimate.

Sell ​​gold

Jewelry stores and workshops sometimes offer not only to buy from themselves, but also buy gold items. In this case, a thorough assessment of the gold will also be carried out and a realistic price will be offered for it. In pawnshops the situation is completely different. Money there, as a rule, is issued on the day of application. In this case, the product assessment will be carried out as carefully as in a bank or jewelry store, with confirmation of the confidentiality of information. For many people this is quite attractive.

Selling to private buyers is an unreliable method. Some dishonest businessmen can easily deceive the seller when weighing, assessing the uniqueness and determining the cost of a product. Due to constant price fluctuations in the precious metals market, the price of gold can quickly change in favor of either the seller or the buyer. Private buyers have to be contacted in the case of raw or illegal gold, as well as after gold products are not accepted at a bank, pawnshop or jewelry workshop.

The purchase of products in the presence of gold in radio components, printed circuit boards or production waste is carried out by specialized companies. You can donate radio components in the region using advertisements from such companies on the Internet.
