Summary:PCT No. PCT/JP86/00203 Sec. 371 Date Dec. 23, 1986 Sec. 102(e) Date Dec. 23, 1986 PCT Filed Apr. 24, 1986 PCT Pub. No. WO86/06418 PCT Pub. Date Nov. 6, 1986.Disclosed herein is a process for dissolving and recovering noble metals form used catalysts. Noble metal components are leached out from particles supporting or containing at least one noble metal or noble metal compound by subjecting particles them to electrolysis, with the electrolyte being an acid, in the anode compartment of an electrolytic cell which divided by a diaphragm into anode and cathode compartments, and the resulting solution containing noble metals is subjected to electrolysis in a fluidized bed electrolytic cell, thereby causing the noble metals to separate out on to the fluidizing cathode particles. The thus deposited noble metals are again leached out in an electrolytic cell.
