flotation in coal mining process

flotation in coal mining process kim-hagen.de

Coal flotation is found to follow a first order process with the coal floating much faster than either pyrite or ash. This circumstance may be used to achieve gangue rejection during flotation. When floated with MIBC, cresol, or pine oil frothers, coal floats in the size sequence: 208 µm (−65 mesh), 589 × 208 µm (28 × 65 mesh), and 1.17

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.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.
