A method for producing a solution containing a monovalent copper metal ion solution from copper metal waste.

摘要

PPROBLEM TO BE SOLVED: To provide a method of producing a solution containing a monovalent copper metal ion solution by dissolving copper metal waste. PSOLUTION: A bivalent copper ion solution is introduced into a dissolution tank in which copper metal waste and a complex compound are present. The copper metal waste is subjected to dissolution treatment to produce the resultant monovalent copper ion-containing solution. PCOPYRIGHT: (C)2003,JPO
