Electrolytic refining of metals from solid starting material containing metal to be refined, comprises contacting starting material with cyanide-containing leaching solution, electrolytically depositing metal, and partially reacting cyanide

摘要

Electrolytic refining of metals from a solid starting material containing metal to be refined, comprises contacting the starting material with a cyanide-containing leaching solution, such that the metal is at least partially present in solution, electrolytically depositing the metal from the cyanide leach solution, and at least partially reacting the cyanide.
