Celanese - The chemistry inside innovation

In these cases, the initial ore could contain between 0.1-0.5% of the desired metal or mineral and following the flotation process the grade can increase to 20-25%. However, the froth flotation process is also used to extract coal, iron, potassium chloride, phosphates, and – in the paper recycling industry – for deinking paper fibers.

Froth flotation is widely used in the coal industry to clean -28 mesh fine coal. A successful recovery of particles by flotation depends on efficient particle-bubble collision and attachment with minimal subsequent particle detachment from bubble. Flotation is effective in a narrow size range beyond which the flotation efficiency drops drastically.
