Patent GB-373596-A (GB)
Title: Improvements in process of recovering metals
IPC: C22B13/00
Filed: 1930-11-21
Abstract: Ores and other metalliferous materials are smelted with sulphur-bearing material and a flux such as soda ash and silica to produce aggregates of sulphides which spontaneously fall to powder from which metals are subsequently recovered.  The resulting slag may be used in enamelling pottery or bricks.  The sulphide powder may be used as a basis for a paint.  To recover metals from the sulphide powder it may be treated with a cyanide to recover gold or silver, or with alkalis to form soluble compounds of gold, tin, antimony, &c., the mixture being electrolyzed with the cathode at or near the top of the solution and the solid material resting on the anode, the solid residue which remains after the metals have been deposited, or in some cases the original sulphide powder, being heated to volatilize sulphur to give metallic or oxide powder which is further treated. It may be smelted with lead to obtain gold, platinum, &c. or melted with a flux and electrolyzed; or the oxides may be electrolyzed without first smelting.  In the electrolytic processes, the electrodes are preferably of lead. The metallic or oxide powder may be treated by wet methods for the extraction of copper, gold, silver, and other metals; for example copper may be extracted with ammonia. If the oxide powder contains much iron it may be extracted with hydrochloric acid and the solution electrolyzed using an iron anode. For the recovery of gold and silver, the oxide powder may be electrolyzed with cyanide solution.ALSO:Ores and other metalliferous materials are smelted with sulphur-bearing material and a flux such as soda ash and silica to produce aggregates of sulphides which spontaneously fall to powder from which metals are subsequently recovered.
