An overview of reverse flotation process for coal
Flotation is one of the most effective technologies for the up gradation of coal fines of particle size below 0.5 mm because of the inherent hydrophobic nature of coal ntrary to this reverse flotation of coal in which coal particles are depressed and gangue particles floated was developed as an alternative process to minimise the sulphur content in the coal.
