Froth floatation

Vedclass · Answer

(C) The concentration of sulphide ores is typically carried out using the $Froth$ $Floatation$ method.In this process,the finely powdered ore is mixed with water and pine oil in a tank.Compressed air is blown through the mixture,creating froth.Since sulphide ores are preferentially wetted by oil,they stick to the froth and rise to the surface,while the gangue particles (impurities) are wetted by water and settle at the bottom.The froth containing the concentrated ore is then skimmed off.
