Froth Flotation (Sulphide & Oxide) ... People used to float -0.5mm coal in flotation cells in 1960s,70s and 80s, but now they have switched to -0.25mm flotation. It is recommended that maximum size particle that you try to float be 0.3mm. The reason is that 0.5mmx0.25mm flotation requires more residence time than 0.25mmx0 flotation.

Effect of polyaluminum chloride on coal flotation ...

 · 1. Introduction. Froth flotation is a particle separation method widely used to upgrade raw coal in fine particle size fraction. Central to this method is to enable air bubbles in water to selectively pick up hydrophobic coal particles, with the formed bubble-particle aggregates rising up to the froth phase to be discharged as product, while the hydrophilic gangue particles are left behind.

Studies on Separation of Macerals from Coal by Froth ...

In the past coal maceral separation have been carried out based on density difference e. g., sink-float analysis, density gradient centrifugation (DGC) techniques etc. These approaches are of limited success. Froth flotation is a physico-chemical process separating particles on the basis of difference in surface properties in a vessel consisting of two distinct zones viz., pulp and froth zones.
