A low grade graphite run-of-mine (r.o.m) ore from eastern India was studied for its amenability to beneficiation by flotation technique. The petrography studies indicate that the ore primarily.
Graphite ore is mostly beneficiated using flotation separation techniques. The increasing demand for high-grade graphite products with up to 99.99% carbon has resulted in the development of various.
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. It has been found difficult to recover refined graphite from rough concentrate.
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 obtained by flotation. Flotation graphite concentrate grades can usually reach 80%-90%, using multi-stage grinding, the purity can reach 98%.

Graphite Concentrate Graphite is a soft, black, lustrous mineral composed of carbon in a hexagonal crystalline structure. It is found in three different forms: in high-grade metamorphic rocks as disseminated crystal flake graphite; in veins or fractures as vein graphite; and in thermally metamorphosed coal deposits as amorphous graphite.
A final concentrate of 8.97% weight recovery with 5.80% ash and 92.13% fixed carbon could be achieved. Key words: low grade graphite, liberation, froth flotation, regrinding, refractory. 1. Introduction Graphite is one of the two naturally occurring allotropes of crystalline carbon and the other being diamond. Graphite is lustrous
