COMPARISON OF FROTH FLOTATION AND GRAVITY

2015-2-1  Combining reflux classification and froth flotation will give better results (coal recovery desulfurization) compared to using two-stage froth flotation. This is because coal flotation is based on hydrophobicity of coal, while gravity separation takes advantage of the large difference in densities between coal and pyrite.

Improving column flotation of oxidized or ultrafine coal ...

2018-8-1  Flotation is effective in a narrow particle size range, beyond which the flotation efficiency drops sharply. In coal flotation, it is a common practice to de-slime flotation feed and divert the ultrafines (−0.1 mm) to tailing dams because the technological constraints of coal flotation are dependent on ultrafines (Clarkson, 1991).
