this method is used for concentration of sulphide ores of copper, lead and zinc. in this method, powdered ore is put in a tank full of water. and then, some pine oil is added to it. in the tank the particles of sulphide ore are wetted by pine oil whereas the gangue particles are wetted bywater. then air is passed through this mixture.

Why is the froth flotation method only used for sulphide

Why Is The Froth Flotation Method Only Used For Sulphide

only sulphide ores are concentrated by froth flotation process because pine oil selectively wets the sulphide ore and hence brings it to the froth. this method is also used in waste recyling and paper industries.. this method also seperates hydrophobic substances from hydrophilic substances..
