Froth Flotation - an overview ScienceDirect Topics

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.
