Assertion : Sulphide ores are concentrated by Froth ...
· Sulphide are particels are preferentially wetted by oil, become lighter and rise to the surface along with the froth while gangue particle are preferentially wetted by water, becomes heavier and thus settle down at the bottom of the tank and cresols stabilise the froth in froth floatation method.
Formation of froth is main reason for extraction of metal.
Sulphide Mineral Indiors For Gold – BC Gold Adventures

In the pressure leaching process, sulphide ores and concentrates are leached in autoclaves at temperatures of 200 to 220°C and a pressure of about 3000 kPa (Schlesinger et al., 2011). An oxidizing agent, usually oxygen, is required to oxidize sulphide ions to sulphate ions. The oxidation of sulphur to sulphate is exothermic; consequently, a
