As gold mining progresses, rich and freemilling ores which are metallurgically easy to process eventually get depleted. More metallurgically complex ores are encountered. These ores yield gold recoveries below 80% and are termed refractory ores. The South African gold mining industry has left a legacy of abundant tailings dams – some of
