The use of thiosulfate to extract gold from refractory ores is promising because of its non-toxicity and high selectivity. Sulfide minerals (i.e., pyrite, arsenopyrite, chalcopyrite), major gold carriers in refractory gold ores, however, hinder gold extraction due to the high consumption of a lixiviant. In this study, a new method to improve gold …

Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as doré – typically containing between 60-90% gold. During its life, a number of factors – such as the price of gold or input costs – will affect which areas of an ore body are deemed profitable (economic) to mine.

The remainder of the ore is made up of quartz, chlorite, sericite and carbonate. A sample of the ore is ground to 80% passing 75 µm, and is subjected to a standard gold cyanide leach test in the laboratory. Gold recovery from this test is 58%. A second sample of the same ore is then floated in the laboratory to recover the sulphide fraction.
