Evaluation of the Cyanidation Leaching of Gold in a Waste Rock Ore [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2014 Samples of the waste rock obtained from Marofengin South Africa ground 60, 70 and 80% passing 75µm were leached with cyanide in bottle roll tests. The results obtained showed that the percentage gold dissolution depends more on the ore size consists than
