Method for preparing nickel-zinc-copper or nickel-zinc alloy electroplating solutions from zinc-containing waste articles having a nickel/copper electroplating layer

摘要

A zinc-containing waste article is recycled by a method in which the zinc of the waste article is recovered in a molten state while the unmolten nickel/copper electroplating layer of the waste article is dissolved in an acidic solution to form a nickel-zinc alloy or a nickel-zinc-copper alloy electroplating solution.
