Flotation of graphite - ScienceDirect

This paper reviews the flotation of graphite. First, the natural floatability and surface properties of naturally hydrophobic solids, including mainly graphite, are discussed from a surface-chemical viewpoint. Then, general aspects of graphite flotation are briefly explained. Finally, the recovery by flotation of kish graphite, which exists in flue dust occurring during the iron and steel

Graphite ore flotation processing flow chart

The flotation method is a relatively common method for purifying minerals. Since the graphite surface is not easily wetted by water, it has good floatability and is easily separated from impurity minerals. The flotation of graphite ore is generally carried out by positive flotation followed by reverse flotation of the flotation concentrate. A higher grade graphite concentrate can be
