EXTRACTION OF COPPER - University of Technology, Iraq

EXTRACTION OF COPPER FROM SULPHIDE ORE Large amount of copper are obtained from copper pyrite (CuFeS2) by smelting. Ores containing 4% or more copper are treated by smelting process. Very poor ores are treated by hydro-metallurgical process. EXTRACTION OF COPPER BY SMELTING PROCESS Following steps are involved in the extraction of

Gold ores containing copper and zinc require uneconomically high quantities of cyanide to process due to the solubility of copper and zinc in cyanide. In practice, to avoid excessive cyanide consumption by copper and zinc, the roasted alcine is usually acid leached to dissolve copper and zinc prior to cyanidation [5]. Ores containing gold tellurides may also be

Extracting from low grade ores - FLSmidth

Extract copper and gold from low-grade ores more efficiently. Ore deposits are becoming increasingly complex to treat and grades continue to deteriorate in known reserves. For instance, approximately 15-20 per cent of the world’s current gold production involves refractory ores that must be pre-treated prior to downstream recovery by cyanidation.
