Concentration of Ores

Froth Floatation Method: This method is commonly used for the concentration of the low-grade sulphide ores like galena, PbS (ore of Pb); ZnS (ore of zinc) etc. and is based on the fact that gangue and ore particles have different degree of wet ability with water and pine oil; the gangue particles are preferentially wetted by water while the ore particles are wetted by oil.

Explain the froth floatation process?

This process is called concentration of ore. This process is mainly used for sulphide ores. The principle of froth flotation process is that sulphide ores are preferentially wetted by the pine oil, whereas the gangue particles are wetted by the water. In this process, a suspension of a powdered ore is made with water.
