Abstract:
A process is provided in which a silver- and base metal-containing material is contacted with an aqueous solution comprising an alkali and/or alkaline earth metal halide and an oxidant at a solution pH of at least about pH 6 to dissolve the silver into a pregnant leach solution while maintaining at least most of the base metal in the silver- and base metal-containing material.
