Flowsheet Options For Processing Copper Gold & Gold …
The presence of copper sulphides in the ore reacting with cyanide requires oxygen similar to gold, according to Elsners equation. If the ore has 7 ppm Au and 460 ppm copper then it is not hard to see the effect on the oxygen demand. Oxygen sparging will assist, however if the oxygen level drops then the leach kinetics will be affected.
