Working directions are given for the dissolving of platinum and palladium scrap, then for the chemical process of creating insoluble compounds that can be recovered by filtering. The treatment of the solids for the recovery of the metals is described and discussed, and the chemcial equations that describe the process will be given. Comments about this chemistry and suggestions about air and water pollution will be included. The treatment of valuable final solutions will be discussed. This method is based on that given by Hoke and on the work in our small refinery near Houston, Texas.
