Coal Flotation SpringerLink

Coal flotation of fine material has both economical and environmental benefits by recovering as much coal as possible from run-of-mine coal and by reducing air and water pollution due to the elimination of sulfur from clean coal and reduction in the solid amount which goes into the stream or in recirculating plant water. Coal flotation is characterized by the chemical and petro-graphical composition of coal

Improving The Performance Of Froth In Coal Flotation

Despite the importance of froth stability, many coal flotation plants encounter overly stable froth problems especially when saline water is used. For example, at a fine coal flotation plant in Queensland, over-frothing occurs due to the formation of stable froth. Residual froth layers on filters cause high moisture of flotation products.

Froth Flotation Cells by Parnaby Cyclones

Fine coal can be separated from shale and other waste by using a process including froth flotation cells. 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

Physical and chemical interactions in coal flotation ...

2003-9-29  Coal flotation is a complex process involving several phases (particles, oil droplets and air bubbles). These phases simultaneously interact with each other and with other species such as the molecules of a promoting reagent and dissolved ions in water. The physical and chemical interactions determine the outcome of the flotation process.

Coal froth flotation: effects of reagent adsorption on

2006-5-15  The -53 {mu}m 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).

ISO 8858-2:2004 sets out a laboratory sequential procedure for the froth flotation testing of fine coal, e.g. coal having a particle size of less than 0,5 mm. The procedure provides a means of evaluating for a coal the flotation characteristics (expressed as a yield/ash relationship) that may be expected from the froth flotation process.
