Precious metals

Directory "Precious metals" on the content in various devices, equipment, components, radio-electronic components.

The automobile industry is the main consumer of mined palladium and rhodium. Together with platinum, they are used in the production of automobile catalysts, since all these metals have high catalytic properties. The purchase and processing of palladium catalysts is a pressing issue for the industry, as this will allow some of the expensive metals to be returned to the industry. However, precious metals in cars contain not only catalysts...

Automotive production in all countries actively uses platinum group metals and silver; gold is used little in this industry. Silver is used for the production of automotive electronics - switches, pressure sensors, alarms, as well as for battery plates with improved characteristics. For breakers, voltage regulators, emergency sensors, some relays, tachometers, in addition to silver, platinum and gold are also used; generators contain palladium. Rhodium has good reflective properties; it is used to cover the surface of headlights and mirrors. Platinum and the rare earth platinoid iridium are found in modern automobile spark plugs.

Various spark plugs contain alloys of platinum, silver, iridium and yttrium. The use of expensive metals is due to the high quality of the parts produced, which increases the reliability of ignition, increases their service life and saves the cost of necessary replacement. Spark plugs with precious metals have a central electrode of small diameter, coated with platinum or iridium - 0.8 mm and 0.5 mm, respectively. The thin electrode provides a voltage concentration higher than on a conventional spark plug, a more stable flame front and slight cooling. But if it were made of an ordinary nickel alloy, it would fail after a few hundred kilometers, while iridium and platinum spark plugs last much longer due to the refractoriness and strength of these metals. Iridium spark plugs have better performance than platinum plugs, and they are equipped with Western cars of the middle and high price segment, and at one time they were intended only for racing cars and aircraft engines. Despite the fact that iridium is a rarer metal than platinum, it costs less and is this moment The production of spark plugs takes about a fifth of all mined metal.

But, despite the presence of precious metals in parts, recycling of automobile scrap is of interest primarily for non-ferrous metallurgy, with the exception of automobile catalysts with a high content of platinum and palladium, as well as some automotive electronics. You can sell a car catalyst that has already served its purpose to our company. We are ready to offer a high price and accept parts from any city in Russia!

Recycling issue used Vehicle , as well as details, is relevant for both organizations and individuals.

Vehicle to be scrapped contains many valuable components, such as , and .

About which ones, how many there are and where are they concentrated, will be discussed in this material.

The main precious metals contained in parts of vehicles such as KAMAZ 4308 are gold and silver, as well as platinum, rhodium, palladium and iridium.

The table below shows some information available on the content of precious metals in Soviet-made cars according to the “List of motor vehicle products containing precious metals” dated 02/24/2000.

As can be seen from the presented data, the most significant content in terms of the total weight of the car is silver:

Gold and silver

Cars usually contain gold and silver as part of electronic components:

relay for sockets, thermostats (silver);
sensors for measuring fuel level (silver);
diodes (silver and gold);
contacts (gold);
voltage regulators (silver);
switches (ignition switches)/switches (silver);
windshield wipers (silver).

In modern cars these metals contained in chips and monitors of on-board computers components that make up the vehicle control and navigation system.

Platinum group elements

Metals platinum group, namely, platinum-palladium-rhodium systems are usually contained in engine catalysts.

With the improvement of engine quality, the amount of rhodium decreased from 18% to 9-10% of the total mass of metals.

When improving engines the amount of rhodium decreased from 17-20% to 9-11% of the total mass of platinum group metals.

When using ternary platinum group systems, it is usually platinum is found in the largest amount, its content is 300-1000 µg/kg, palladium - 200-800 µg/kg, rhodium - in the range from 50 to 100 mg/kg.

Precious metals in automobile catalysts

As mentioned above, modern catalysts include platinum, palladium and rhodium. In addition, in the automotive industry of Germany and the UK for the production of automotive catalysts iridium is widely used.

In many cases, the catalysts of cars produced in these mills are sorted separately as potentially containing this precious metal.

Waste enrichment methods

To solve the problems of processing automotive components containing noble metals, use hydrometallurgical and pyrometallurgical methods.

The source for processing (in the case of a catalyst) contains a large number of ceramic carrier and a small concentration of precious metal.

When recycling electronic waste the source is scrap components, usually containing plastic particles.

The task of recycling waste automobile parts is to obtain semi-finished products suitable for recycling.

Hydrometallurgical method for extracting precious metals consists of the following main steps:

primary leaching of waste with mixtures of acids, the composition of which depends on the qualitative and quantitative content of precious metals in the source material, at temperatures above 100 °C;
repeated washing of the acid-insoluble carrier with water;
drying the semi-finished product at 200 °C and calcination at temperatures of about 600 °C.

Examples of using the hydrometallurgical method enrichment during the processing of catalysts for Mercedes-Benz, Honda, Volvo cars based on platinum group metals presented in patent 2209843 “Method for extracting platinum metals from autocatalysts” by V.A. Shipacheva. 2008.

When using the pyrometallurgical method, waste processing occurs in next few stages:

Crushing the feedstock and sorting its particles by size.
Preparation of the initial mixture.
Melting of crushed product at a temperature of 3000 °C in a plasma-arc furnace to form melts of precious metals, ceramics and metal carriers.
Periodic draining of slag melts, stratified due to the difference in the densities of metals and ceramics: the ceramic melt remains at the top, the precious metal melt in the collector metal (iron) is drained from the furnace.
Granulation of liquid melt containing precious metals.

Final product granulation, 3-15% enriched with precious metals, is a suitable raw material for refining industries, further highlighting precious metals with the highest degree of purity.

Examples of processing electronic parts using this method are presented in patent 2521766 “Method for processing electronic scrap” by V.V. Elders. from 07/10/2014.

Sale of spent catalysts

Spent catalysts can be sold to a number of companies, related to refining enterprises contracts for the recycling of enriched raw materials received by them.

The scope of activities of such companies includes the purchase of spent catalysts from individuals and legal entities, determination of which of the platinum group metals and how much is contained in them, and their primary processing.

Contacts of these companies are available through websites, information on the procedure for accepting and paying for the delivered catalyst is also provided there.

Examples of these companies include the following organizations:

Based on the results of the analysis, the value of the transaction is determined. On average, for foreign cars prices for 1 kg of catalyst vary from 5,000 to 15,000 rubles, depending on the car brand.

Thus, catalysts for Hummer, Land Rover, Infiniti, Jeep GrandCherokee, Lexus, and Mercedes-Benz vehicles reach the highest cost.

Prices for domestic catalysts are indicated around 1,500 rubles/kg.

Conclusion

Disposal car parts for the purpose of obtaining financial gain due to the extraction of noble metals from them into modern conditions is a solvable problem both for legal entities and individuals.

To do this, the customer should contact the appropriate company engaged in the reception, evaluation and primary processing of automotive raw materials in order to obtain concentrates for subsequent fine processing and metal production high quality or involving them in recycling.
