Vedclass · Answer

(A) The froth floatation process is used for the concentration of sulphide ores. In this process,the 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 molecules (like pine oil or xanthates) adsorb onto the surface of the ore particles,making them hydrophobic and allowing them to attach to air bubbles and rise to the surface as froth.

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