Vedclass · Accepted Answer

It helps in the preferential wetting of sulphide ores by oil,allowing them to rise with the froth.

Vedclass · Answer

(B) In the froth floatation process,the sulphide ore particles are preferentially wetted by the pine oil (collector),which acts as an adsorbent on the surface of the ore particles. This makes the ore particles hydrophobic (water-repelling),allowing them to attach to air bubbles and rise to the surface as froth. Conversely,the gangue (impurities) is wetted by water and remains in the bottom of the tank.

What is the role of adsorption in the froth floatation process used especially for the concentration of sulphide ores?
