Ans The first process in the extraction of zinc is the concentration of the ore which is done by the Froth Floatation method It is based on the principle that the gangue and ore particles have different wettability degrees with water and pine oil The ore particles being hydrophobic in nature are wetted by oil whereas gangue particles being hydrophilic in nature are wetted by water
