Platinum recovery from platinum catalyst
Platinum exists in the form of platinum particles in the catalyst and is widely used in automotive catalysts, chemical reaction catalysts, petroleum refining, etc.
1. Pretreatment of platinum catalyst recovery: First disassemble the shell, then crush it into powder.
2. Platinum dissolution and leaching: Soak the platinum catalyst in hydrogen chloride solution to dissolve the platinum in it.
3. Extraction + purification: Use a specific organic solvent to separate the platinum.
4. Processing: After two cleaning and filtration, the platinum has been recovered from the platinum catalyst.
Then it is smelted at high temperature and cast into ingots.Platinum catalyst
