Froth flotation dates back to the late 19th century and was the first method developed by the mining industry to separate minerals from ore. Froth Flotation, which is also used in the paper recycling and waste-water treatment industries, works on the principles of density as well as the water properties of mineral particles.

Froth Flotation. Froth flotation is a surface chemistry based separation process which is extensively used in the processing of mineral ore deposits as a method of separating the desired mineral component from their associated gangue material [17,34]. From: Advances in Colloid and Interface Science, 2005.
