Vedclass · Answer

(B) The froth floatation process is primarily used for the concentration of sulphide ores. In this method,the ore particles are preferentially wetted by oil (pine oil),while the gangue particles are wetted by water. $A$ strong current of air is blown through the suspension,creating a heavy froth. The sulphide ore particles,being wetted by the oil,attach to the air bubbles and are carried to the surface as a froth,which is then skimmed off. The gangue particles remain in the water and settle at the bottom.
