Reduction of Sulfur and Ash from Tabas Coal by Froth

2021-8-6  In the conventional flotation process, the pulp in a flotation cell is agitated to obtain particle suspension, and the mechanism of agitation permits entrainment of air into the cell. This air is dispersed as fine bubbles. During the flotation, the bubbles rise to the surface of the pulp, and a froth zone is taking place. In froth flotation, both water and solids are recovered into the concentrate from the level of the

The characteristic feature of the flotation process is the interaction of gas bubbles with solid particles in a dispersion medium. This monograph reviews the state of the art from the point of view of colloid science, i.e. the heteroparticle interaction. A number of process engineering aspects and physically-based approaches to modelling the flotation process are also taken into account.
