Palladium and platinum recycling process Due to the wide variety of secondary resources of palladium and platinum, the grades are different, and the impurity content is different. It is necessary to formulate a reasonable recovery process according to the characteristics of different secondary resource materials. Spent catalyst, spent catalyst, spent catalyst car for palladium on alumina (Pt) in general, two kinds of process route, first type are: selective dissolution of the insoluble carrier → → residue was dissolved noble metal → separation and purification. The second type is: dissolving precious metals → separation and purification. The process route for palladium (platinum) carbon waste catalyst, waste electronic slurry and the like is: roasting→baking slag→dissolving precious metal→separation and purification. The process route for the waste palladium (platinum) plating solution is: displacement → displacement slag → dissolved precious metal → separation and purification. For the palladium (platinum) waste electronic components (integrated circuit boards, contacts, contacts), the process route is: classification and disassembly → roasting → roasting slag → dissolving precious metals → separation and purification. It should be pointed out that no matter what kind of process is adopted, it is necessary to have perfect environmental protection facilities. For example, the roaster should be equipped with a complete dust collection facility, and the exhaust gas and waste water can be discharged after being treated to the standard.
