Treating the mixed chlorides with saturated salt solution and metallic copper will reduce the AgCl to metallic silver. The mix of metallic copper and silver can be washed free of copper and lead chlorides by first using saturated salt solution, then hot water. Treating of the mixed metals with sulfuric acid can dissolve most of the copper.
