Vedclass · Answer

(B) The froth floatation process is based on the difference in the wetting properties of the ore and the gangue particles with water and oil. Ore particles are preferentially wetted by oil,making their surface hydrophobic (water-repelling). Because their surface is not easily wetted by water,they attach to the air bubbles and rise to the surface along with the froth. Gangue particles are preferentially wetted by water and remain in the aqueous phase.

In the froth floatation process for the concentration of ores,the ore particles float because:
