This method of concentration of the ore is based on the difference in specific gravities of the metallic ore and gangue particles. Generally metal ores are heavier than the gangue associated with them. By flowing the powdered ore in a current of water, the lighter rocky impurities can be washed away and the ore particles are left behind.
