Improving the gold leaching process of refractory ores

4/1/2019· The mineralogy of gold ore deposits ranges from free-milling, metal oxide ores, to sulphides. The sulphide ores tend to be refractory to leaching when employing a normal cyanidation process. Recoveries of gold, when employing a normal cyanidation process in the treatment of sulphide ores, tend to be less than 80%.
