Sulphide ores are generally concentrated by
1 Froth floatation process
2 Magnetic separation
3 Gravity separation
4 By hand picking
Explanation:
(a)Froth floatation method is based on the fact that the surface of sulphide ores is preferentially wetted by oil while that of gangue is wetted by water.

Froth floatation process is used for the concentration of
1 Oxide ores
2 Sulphide ores
3 Chloride ores
4 Amalgams
Explanation:
Froth floatation process is used for the sulphide ores. In this method, wetting of the ore by an oil takes place. A strong current of air is blown through the suspension, producing a heavy froth or foam on the surface. The metal sulphide is wetted by the oil but the gangues is not and the sulphide-oil mixture is carried to the surface by films of oil The froth is skimmed off, the gangue settles down on the bottom or remains underneath the froth.
