  • Froth Floatation Process

    Froth Floatation Process 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. This results in the agitation of water in tank, which cause the sulphide ore particles to stick with the oilОнлайн-запрос
