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.

The existing mechanical floatation cells treat fine coal particles(<500 micron) recovers clean coal using air bubbles by utilising the difference in hydrophobicity of coal and ash. Uniform distribution of fine ash particles on the surface of coal particles makes its recovery difficult.
developing an ultrafine, {-400 mesh) advanced physical coal cleaning process - ISGS Aggregate Flotation CAFl. The basic process incorporates aspects from both oil agglomeration and froth flotation. Extensive chemical, petrographic and mineralogical support has aided in delineating appropriate process .
The aggregates formed were then separated from gangue by aeration in a flotation machine. This allows for almost complete recovery of coal. Preliminary aggregation of coal grains made it possible to eliminate the frothing agents usually needed in such a process.

The purification of high-ash fine coal is limited by the fine particle size. On one hand, fine pure coal particles are difficult to be captured by bubbles due to the lower collision probability between them; on the other hand, fine clay particles are often recovered by entrainment due to their lower mass, which result in the pollution of the clean coal.

Sep 29, 2003· The physical and chemical interactions determine the outcome of the flotation process. Physical and chemical interactions between fine coal particles could lead to aggregation, especially for high rank coals. Non-selective particle aggregation could be said to be the main reason for the selectivity problems in coal flotation.

The amenability of beneficiating a fine hard coal from Hwa-Sun coal mine using column flotation has been studied using a CoalPro flotation column developed by Canadian Process Technologies (CPT). After initial testwork using a batch flotation cell to determine the optimal flotation conditions, tests were carried out to compare its performance with the column.
