How many grams of precious metals can be refined by three-way catalysis?How much is a catty of three-way catalytic powder

1 catty of threeYuanThe catalytic converter can extract 0.1 to 2.5 grams of precious metals, and the amount of extraction depends mainly on the quality of the recovered three-way catalytic converter. If the quality of the three-way catalytic converter is better or the use time is short, then more precious metals will be extracted. If the quality of the three-way catalytic converter is poor or the use time is long, then the refined precious metals will be less. The price of the recycled three-way catalytic converter is determined according to the quality, if the quality is worse, it will cost a few hundred dollars, if the quality is better, it will cost thousands of dollars.

How much is a catty of three-way catalytic powder

According to the price statistics of three-way catalytic powder on the market, most of the three-way catalytic powder is about 2,000 yuan per catty. The reason why the three-way catalytic powder is so expensive is mainly because the inside of the three-way catalytic converter contains rare metals such as palladium, rhodium, and platinum. The prices of rare metals are relatively expensive. The catalyst inside the three-way catalytic converter is ground into powder. Later, the price is naturally expensive.

Three-way catalytic converter is expensive to refineThe metal method is:

1. Grind the catalyst inside the three-way catalyst into powder. The outside of the three-way catalyst is iron, the inside is ceramic, and the precious metal is a layer of catalyst coated on the inside;

2. The powder ground from the catalyst is burned at a high temperature;

3. Add sodium borohydride aqueous solution and cook to 100 degrees, then add sodium chlorite hydrochloric acid solution;

4. The temperature will continue to be around 100 degrees, and it will slowlydiscoverThere will be particles under the solution, which can be filtered after 3 hours, and solid particles can be obtained after the filtration is completed;

5. Add 10% HC1 and aqueous solution for pickling and water washing. Keep it at about 100 degrees. After separation, platinum metal can be obtained.
