Copper Gold Ore Treatment

A typical copper ore would be 0.7 to 2 copper, a typical copper concentrate would grade around 25 to 35 copper. Copper concentrates are either smelted and refined in-house, or sold to custom smelters. The concentrate may be smelted to produce blister copper for sale to a custom refinery, or the blister copper may be refined to cathode.

Extract copper and gold from low-grade ores 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.

Abstract. Problem ores that yield low (say less than 80 ) gold recovery by cyanidation when “normally ground” are defined as refractory. The term, as well as the technical methods used to treat such ores, are relatively new. Rose and Newman’s very comprehensive book, The Metallurgy of Gold, does not even contain the term refractory in its.
