Abstract
1516127 Recovering metals from sulphide ores CYPRUS METALLURGICAL PROCESSES CORP 27 Aug 1975 [21 Oct 1974] 35281/75 Heading C1A Lead, silver and zinc values are recovered from sulphide ores or concentrates by chlorinating to convert the sulphides into chlorides and sulphur, leaching with sodium chloride solution to extract the chlorides, removing lead chloride from the leach solution by crystallization, recovering silver from the lead depleted solution, preferably by cementation, and removing zinc from the lead- and-silver-depleted solution e.g. by precipitating the carbonate using Na 2 CO 3 . A portion of leach solution is returned to the leaching step after removing the lead and some or all of the silver and optionally the zinc. Part of the depleted solution may be electrolysed to produce chlorine gas for the chlorination step. Antimony in a galena/tetrahedrite ore concentrate is volatilized as the chloride if the chlorination is carried out at 50-150C.
