2009-8-27 1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air bubbles are then carried to the surface and

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.

Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the froth must travel increases with an increase in the ...
