Abstract

The lead and silver in complex sulphide ores containing zinc such as Broken Hill ores and similar materials are converted into chlorides by mixing the ore with hydrochloric acid in quantity sufficient for the desired reaction and heating to a temperature above 100 DEG C. The ore is mixed with the acid, dried at a temperature below 100 DEG C., and heated at a higher temperature which may be 500-600 DEG C., preferably in a closed vessel. The operation is facilitated if some copper is present in the ore. The mixture of ore and acid may be allowed to stand some time before drying, and the furnaced product may be moistened and left for some time before leaching. The product may be leached with hot brine containing some ferric chloride to dissolve both lead and silver chlorides with a minimum time of contact between liquor and ore.
