Document Type and Number:
Japanese Patent JP7392538
Kind Code:
B2
Abstract:
The present invention provides a method for treating an alloy, wherein nickel and/or cobalt is obtained by separating copper and zinc from an alloy that contains copper, zinc, and nickel and/or cobalt. The present invention is a method for treating an alloy, by which a solution that contains nickel and/or cobalt is obtained from an alloy that contains copper, zinc, and nickel and/or cobalt, said method comprising: a leaching process wherein a leachate is obtained by subjecting the alloy to a leaching treatment by means of an acid in the coexistence of a sulfurizing agent; a reduction process wherein the leachate is subjected to a reduction treatment with use of a reducing agent; and an ion exchanging process wherein a solution that contains nickel and/or cobalt is obtained by bringing a solution, which has been obtained in the reduction process, into contact with an amino phosphoric acid-based chelate resin, thereby having zinc adsorbed on the amino phosphoric acid-based chelate resin.
