Answer 2

Froth flotation is used for concentrating sulphide ores e.g. zinc blende and copper pyrites.
A mixture of the sulphide ore, water and a suitable oil is taken in a tank. Air is passed, under pressure, through the mixture. A froth is then formed in the layer of oil. The sulphide particles adhere to the oil,and the muddy impurities remain in the waters.So,the sulphide particles rise up with the froth. The froth is collected and the oil is squeezed out to isolate the sulphide paricles
