This process is called concentration of ore. 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. In this process, a suspension of a powdered ore is made with water.

Froth Flotation (Sulphide & Oxide)

Froth floatation process is based on the principle that the metallic sulphide particles of ore are preferentially wetted by oil and the gangue particles by water. Collectors attach themselves by polar groups to grains of minerals which then become water repellent and thus, pass on into the froth. Examples are ethyl xanthate and potassium ethyl xanthate.

Here potassium ethyl xanthate acts as a collector. $ce{KCN}$ and $ce{NaOH}$ depress the floatation property of $ce{ZnS}$ and $ce{FeS2}$ particles. Thus, only $ce{PbS}$ particles go into the froth. Now copper sulphate is added to the mixture which activates floating character of $ce{ZnS}$ and this time only $ce{ZnS}$ comes along with froth.
