Froth floatation method is commonly used for the concentration of the low-grade sulphide ore. The principal is based on the fact that gangue and ore particles have a different degree of wettability with water and pine oil. The ore particles are wetted by oil whereas gangue particles are wetted by water.

Impurities like sand and soil particles existing in any ore are termed as gangue. Elimination of these impurities from ore to extract the metal is termed as enrichment of ore or concentration of ore. Smelting is the process in which the concentrated ore is heated in the presence of a reducing agent like Carbon (C) to extract the desired metal.
