Abstract

Sulphide ores and products containing silver, lead, and zinc sulphides are partially chloridized, for instance by heating with enough zinc chloride to chloridize the silver and lead, and the product, from which the excess of zinc chloride may be removed by leaching with water acidified with hydrochloric acid, is then leached with a solvent such as cold brine containing ferric chloride and which may be saturated with lead chloride, so as to extract the silver alone, and the residue is then leached with hot brine for dissolving the lead chloride.
