froth flotation coal beneficiation

Jun 01, 2015 · Woodburn et al. pointed out that the froth stability had a significant effect on the recovery of low rank coal and a more stability of froth was suitable for the beneficiation of low rank coal. Fuerstenau et al. [108] used non-ionic surfactants as collectors to float both oxidized and low rank coals, and found that both oxidized and low rank

    3 technologies in exploration, mining, and processing

    Flotation is a major separation method for metals, coal, and industrial minerals. Most sulfides can be economically recovered by the flotation process. Parameters that influence flotation can be divided into two general categories: (1) the surface characteristics of the minerals and (2) the design of the flotation …

    Flotation processes treat fine-sized coal with an oil-based reagent that attracts air bubbles in a liquid medium; the coal floats to the surface as froth, leaving the refuse below. Hydraulic processes use currents of water to separate coal from impurities. Pneumatic processes use currents of air to separate coal from impurities

    5. FROTH FLOTATION Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.
