Answer:
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.
(ii) Formation of emulsion takes
place.
(iv) Froth is formed along with
ore particles.
(v) Mechanism of the functioning
of shape selective catalysis.
As sulphide are extracted using froth
floatation method therefore, only sulphide ore particles will show these type
of adsorbing tendency.
