Froth flotation is a complex physicochemical process that is accomplished in two distinct phases in a flotation cell: a pulp phase and a froth phase. The pulp phase

EVALUATION OF FROTHER PERFORMANCE IN COAL

2018-5-29  Separation efficiency in flotation depends, to a considerable extent, on the efficiency of the frother used. A successful frother must achieve a delicate balance between froth stability and non-persistency. Ideally, the frother is not supposed to influence the state of the surface of the coal and minerals. In practice, however, interaction does occur between the frother, other reagents, and

Flotation Circuit an overview ScienceDirect Topics

Froth flotation depends on differences in surface properties between coal and shale. Air bubbles are generated within an aqueous suspension of fine raw coal with a solids concentration of less than 10%. The hydrophobic coal particles attach to the air bubbles and are buoyed to the top of the froth flotation cell where they are removed as froth.
