Principles and Procedures involved in the Extraction of ...
Procedures for Metal Extraction. 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 tin 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.
