Undesired chemical side-reactions during the de-ashing and desulfurization can be avoided – accomplishing the process in much less time. Even during the separation process via froth flotation, the fine-size dispersion of particles can be significantly enhanced by sonication. Coal Liquefaction/ Coal-to …
Froth floatation method is the physical method for the separating mineral from the gangue. (B) It is based on the difference in wettability of different minerals. The metallic sulphide particles of ore are preferentially wetted by oil and the gangue particles by water. (C) Froth floatation process used for the concentration of sulphide ore.
