GCM Hydrocopper Process Update - Silver Recovery from Copper Chloride Solutions

The development of precious metal recovery processes using chloride systems has mostly evolved from the development of chloride based treatments for base metal concentrates or ores. The recovery of silver from chloride solutions within a process designed for the treatment of base metals usually is part of a solution purification stage. This paper discusses the development of the silver recovery stage used in the GCM HydroCopper process.
