Solution

The correct option is B Adsorption of pine oil on sulphide ore particles
In Froth floatation process a low-grade sulphide ore is concentrated by separating it from silica and other earthy matter by this method using pine oil and frothing agent.
Pine oil is adsorbed on sulphide ore particles so as to facilitate the further process.
