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.

What is froth flotation process Class 10? The Froth Floatation method is a method used for the concentration of metal ores. It is used for the concentration of sulphide ores. The ore particles become wet by oil while the gangue particles become wet by water. Air is blown in through a pipe and a rotating paddle agitates this mixture.

Froth flotation is a physico-chemical separation process. Separation is principally based on differences in surface hydrophobicity. However, particle size and density have a significant impact. Initial flotation patent and application was developed for graphite by the Bessel brothers (1877). Similar to graphite, coal is naturally hydrophobic.

The geometry of flotation column offers some advantages over convention cells. Column cells have a much smaller surface area per unit volume of capacity than conventional cells which promotes froth cro wding. This results in higher froth densities, and when coupled with a stabilizing water addition, permits froth depths of 1m - 2m to be maintained.
