Advances in Gold and Silver Processing. HYPOCHLORITE LEACHING OF GOLD ORE 7 1 Free Milling Gold Ore The free milling gold ore used in this study contains sulphide minerals, such as chalcopyrite and pyrite. Conventional cyanidation resulted in 95 of the gold being extracted under strong leaching conditions, i.e., a grind of 90 minus 200 mesh, leach with 1 g5 NaCN at pH 11.0 for . How to
The plant was experiencing problems in the leach, adsorption, elution and electrowinning sections mainly as a result of the presence of copper in the ore. The changes made to the operating standards, the response of the circuit to these changes and the final Circuit layout and operating conditioning resulting in a 90 gold recovery are discussed. It was concluded that the distribution of
