ELECTROLYTIC PROCESS FOR THE RECOVERY OF NICKEL, COBALT AND IRON FROM THEIR SULFIDES

摘要

A pollution-free process for the electrolytic dissolution of sulfide concentrates of the metals of Group VIII of the Periodic Table in aqueous acidic media with the formation of metal ions and elemental sulfur followed by recovery of the metal ion from solution in the electrolyte media, the process characterized by certain critical process conditions, these being the use of:
