Recovery of gold from the Mouteh Gold Mine T tailings dam


The mineralogy of the tailings indicates that froth flotation is the best method of removing the pyrite for separate treatment. However, ultra fine grinding may be used when liberation of gold particles from the surrounding mineral matrix is the primary refractory characteristic of the ore. Roasting can also be used to oxidize both sulphur and
