What is the role of adsorption in froth floatation process ...

In froth floatation process sulphide ore is shaken with pine oil and water, the ore particles are adsorbed on froth that floats and the gangue particles settle down in tank. Thus, role of adsorption in froth floatation process can be understood as following processes. (i) Adsorption of pine oil on sulphide ore particles.
