(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.

Thermal and Structural Study of Low Grade Graphite Ore ...

In this paper an attempt has been made to characterize the low grade calcareous graphite ore from Shivaganga region, India. By judicious combination of structural, thermal and chemical analytical techniques, the liberation size of graphite as well as estimation of minerals are determined to establish a feasible beneficiation process. This data show a good correlation. The ore consists of ...
