What is Froth Flotation? wisegeek

Apr 24, 2019Froth flotation is a process using air bubbles to separate materials based on their relative affinity to water. Bubbles carry reagent and hydrophobic materials to the top of a tank where they can be removed. Froth flotation has been used for more than a century in mining operations to separate valuable materials from excavated ores.

Studies on Separation of Macerals from Coal by Froth

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.

Froth flotation is a widely used, cost effective particle separation process. However, its high performance is limited to a narrow particle size range, e.g., between 50 m and 600 m for coal and between 10 m and 100 m for minerals. Outside this range, the efficiency of froth flotation decreases significantly, especially for difficult to float particles of weak hydrophobicity (e.g
