Mechanized coal mining techniques generate large amount of fine particles that have to be recovered in coal washing plants. Fine coal processing has always been a problematic and costlier than the cleaning of coarse coal (Andrew Mohns 1997).Froth flotation technique is an effective and best available technique for cleaning fine coal with particle size less than approximately 0.5 mm (Bensley ...

Get PriceFroth 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.
Get PriceA full-scale Microcel™ flotation column was trialled at the BHP Coal Peak Downs Mine and Saraji Mine coal preparation plants for the treatment of 0.5 mm × 0 (−500 μm) coal. By using deep froths and counter-current froth washing, the Microcel™ columns have been demonstrated to achieve substantially lower product ash compared to conventional flotation cells when treating slimes fractions.
