Froth flotation Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Removal of unburned carbon from fly ash using enhanced

Different from froth flotation, gravity separation takes advantage of the density differences between unburned carbon particles (~1.8 g/cm 3) and ash particles (~2.5 g/cm 3) , , which led to the distinctions of settling velocity in fluid medium (for example water or air) and promoted the separation of unburned carbon particles and ash particles , .

Mineral processing Wikipedia

Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles.

Celanese The chemistry inside innovation

The remaining material from the ore does not rise to the surface. Separation – The mineral laden froth is then separated from the water bath and the resulting concentrate is further refined to deliver the desired mineral or metal. The remaining “slurry” can be further frothed in a downstream flotation cell.
