  • Froth Flotation Cells - Coal Beneficiation - Parnaby Cyclones

    Operation. Fine coal can be separated from shale and other waste by the process of froth flotation. The coal is made water repellent by the addition of a reagent such as oil, so that when a suspension of coal is agitated with air it sticks to the air bubbles and floats to the surface, collecting as froth. Shale and other waste are not wetted by...

    Aug 17, 2018 · In mineral processing, froth flotation is a major separation process used in the beneficiation of mineral particles and occurs when crushed and ground-up ore is treated with a reagent to make the mineral surface water repellent and causes the valuable mineral to stick to the bubbles.

    The −53 μm size fraction of a bituminous coal was used to perform froth flotation experiments. The froth flotation of the coal used was performed in the presence of two nonionic surfactants, Triton x-100 (poly(ethylene glycol) tert -octylphenyl ether) and MIBC (methyl isobutyl carbinol), and an anionic surfactant, SDS (sodium dodecyl sulfate).

    The sulphur, moisture and volatile matter are same as in the raw coal. Froth flotation at Ph9 of the coal gave an average ash content of6.95% with the fine coal reporting first with less ash content of 3.42%. This difference could be probably due to the presence of pyrite which might have been depressed at Ph9.
