    Introduction ChestofBooks Read Books Online for Free

    Gold terchloride, for lixiviation, usually called simply gold chloride, is made by exposing the pulverized ore, containing the metal in small particles, to the action of chlorine and moisture. It is extracted by leaching with cold water, in which it dissolves readily, and the gold is precipitated in the metallic state, as a brown powder, by a
