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.

Seven Common Froth Flotation Processes - Xinhai

2019-10-18  Froth flotation process is a kind of mineral processing technology that uses the flotation reagents to separate the ore according to the physical and chemical properties of the surface of the ore. The froth flotation process is to grind the mineral to the floating requirement, adjust the pulp concentration and add the flotation reagents, then inflate the air to make the mineralized froth separate.
