Vedclass · Answer

(A) The froth floatation process is used for the concentration of sulphide ores. In this process,the sulphide ore particles are preferentially wetted by the oil (frother),while the gangue particles are wetted by water. This selective wetting is based on the principle of adsorption,where the collector (like pine oil or xanthates) gets adsorbed on the surface of the sulphide ore particles,making them hydrophobic and allowing them to attach to air bubbles and rise to the surface as froth.

Froth floatation process for the concentration of sulphide ores is an illustration of the practical application of
