(PDF) THE BENEFICIATION OF GRAPHITE BY FLOTATION

Graphite is a natural floater. Flotation has become the accepted method of beneficiation of graphite (Crawford and Ralston, 2008). Flake graphite from disseminated deposits is difficult to concentrate, therefore, a number of processes have been evolved by different countries.
