01 The gold ores suitable for the flotation process. In the practice, the flotation method can be considered when the gold-bearing ores have the following characteristics: The gold and sulfide are closely associated; Although most of the gold does not coexist with sulfide, a considerable amount of metal sulfide in the ore has formed a stable foam containing gold sulfide;

gold ore flotation mill in the bahamas
The mill was first commissioned in 1938. The flowsheet at that time was a straight cyanidation circuit. The original mill operated in that mode up to the discovery of the Bousquet 2 orebody in 1989 which consisted of a massive copper sulphide ore averaging 0.7% copper and 7 g/mt of gold. Bousquet 2 ore processing required a mill retrofit.

gold processing - gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for
