Dealing with copper in gold ores; Implemented and future .

 · The main approaches considered to treat coppergold ores or gold ores containing copper are: 1. Flotation to generate a copper concentrate containing gold as a coproduct and cyanidation of the flotation tail and/or other concentrate streams to recover additional gold. 2. Cyanidation of selectively mined ore having low soluble copper. 3.

Gold mineralisation extends over a 1,500m by 400m zone and is open at depth (+400m). The mineralisation is characterised by a simple mineralogy comprising gold, silver, pyrite and minor sphalerite and galena. Metallurgical recoveries of gold average more than 93% for oxide and sulphide ore in the planned open pit.
