Separation Of Coal Froth Flotation

In the past coal maceral separation have been carried out based on density difference e., 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.

Our leading products have crushing equipment, sand making equipment, mobile crusher, etc., Each type of product is with complete specifications. All products have passed ISO9001, CE and GOST international quality system certification.

Is Separated From Rock By Froth Flotation

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.
