WhatsApp: +86 18221755073ENGLISH ABSTRACT: As gold mining progresses, rich and free-milling 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 …
