Principles and Procedures involved in the Extraction of ...

Procedures for Metal . Concentration of Ores: Ores may be concentrated either by i Washing away the earthy materials in a stream of water in order to leave behind the heavier ores as is the case with ore or by ii Froth flotation where the ores are churned up with oil and water to form froth. This froth which contains the ore is skimmed off by blowing air.
