Studies on Separation of Macerals from Coal by Froth ...

In the past coal maceral separation have been carried out based on density difference e. g., sink-float analysis, density gradient centrifugation (DGC) techniques etc. These approaches are of limited success. Froth flotation is a physico-chemical process separating particles on the basis of difference in surface properties in a vessel consisting of two distinct zones viz., pulp and froth zones.

Dec 18, 2016· The frothers having a low water-carrying rate were more selective for producing low-ash content coal, such as 1-Pentanol and MIBC. MIBC showed better flotation performance for all size fractions in terms of kinetics and selectivity. The three frothers present good correlation between the water-carrying property and fine coal flotation performance.
