Palladium, as a precious platinum group metal, is widely used in industry and jewelry manufacturing. The palladium refining process is critical, as it is not only related to the purity and quality of the metal, but also directly affects its market value.
The main method of palladium refining
Wet refining: The raw material is treated with a chemical solution to extract palladium.
Dry refining: purification by physical methods such as high temperature sintering.
Electrolytic refining: The use of electrolysis to separate high purity palladium from mixed metals.
Solvent extraction: Palladium is extracted using a specific organic solvent.
Each method has its advantages and limitations, and choosing the appropriate refining method depends on the type of feedstock and the purity of the palladium required.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47374.html

Recovery of palladium from waste catalyst
Date: June 2023
Location: Kolkata, India
Procedure:
1 Collection and classification: In an automobile repair plant, a large number of palladium-containing waste catalysts were collected.
2 Pretreatment: The palladium in the catalyst is exposed by physical methods such as grinding.
3 Chemical dissolution: The ground material is put into a chemical solution, and the palladium is dissolved.
4 Solvent extraction: The use of organic solvents to extract palladium from palladium containing solutions, this step is key to the removal of other impurities.
5. Electrolytic refining: the palladium solution extracted by solvent enters the electrolytic cell, and under the action of current, palladium is deposited in the cathode to form high purity palladium metal.
6. Smelting and casting: The palladium metal obtained after electrolysis is smelted, the residual impurities are removed, and then cast into palladium ingots.
7. Inspection and evaluation: The final palladium ingots undergo a rigorous quality inspection to determine their purity and weight.
8. Pricing and sales: According to the market conditions at that time, the price of palladium per gram was about xxxx Indian rupees.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/47374.html
