graphite is mainly of vein type and the purities range from 90. Demand for high purity graphite is progressively increasing due to its variety of traditional applications and predicted novel applications. Herein, we describe novel, lowcost and simple flotation technique for graphite concentration and crystallinity enhancement.

Froth flotation takes place in a watermineral suspension. It is used for selectively separating minerals by taking advantage of differences in their hydrophobicity. The surfaces of the graphite particles are hydrophobic (waterrepellent) and it is thus very amenable to flotation in water using suitable/selective conditioning reagents.
froth layer. Particles that are retained in the froth are recovered at the lip of the froth at the edge of the flotation cell. The recovery of the froth is accomplished by the natural mobility of the froth which causes it to flow over the and the recovery is sometimes assisted by mechanical paddles.

In the froth floatation process, the role of the depressants is to separate two sulphide ores by selectively preventing one ore from forming froth. For example, to separate two sulphide ores (ZnS and Pbs), NaCN is used as a depressant which selectively allows PbS to come with froth, but prevents ZnS from coming to froth.
The concentration of copper in ores averages only %, and most commercial ores are sulfides, especially chalcopyrite (CuFeS 2 ), bornite (Cu 5 FeS 4 ) and, to a lesser extent, covellite (CuS) and chalcocite (Cu 2 S). These minerals are concentrated from crushed ores to the level of 10–15% copper by froth flotation or bioleaching.
