Improved Coal Flotation with Sinterol Modifier

The flotation of coal with different ash content when using Sinterol modifier is studied. If the modifier consumption is 1.0–3.0 g/t of coal fines, the extraction of the coal’s combustible mass in the concentrate is increased; the selectivity of the process is increased; and the loss of the coal’s organic mass with the flotation wastes is decreased.

2015-1-10  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.Contrary 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.
