Enhancing gold recovery by bioleaching of chalcopyrite low grade ore
Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult. Treatment of the roasted ores was done by normal methods such as amalgamation or cyanide treatment. Unfortunately, sulfur oxides are also pretty nasty and smelly air pollutants – which is why there are ...
