Since graphite is spontaneously hydrophobic (like coal) in nature, flotation is the common and apt technique for beneficiation of graphite ore. In this study, the research and development on the graphite beneficiation techniques especially flotation reported by several learned research groups in the world has been discussed and presented.
A low grade graphite ore from eastern India was beneficiated by flotation to improve its quality. The ore was composed of 87.80% ash and 8.59% fixed carbon. Primary coarse wet grinding ( d80: 186 μm) followed by rougher flotation in Denver flotation cell using diesel as collector and pine oil as frother yielded a rougher concentrate.

Low-grade graphite ore from Jharkhand, India, with a carbon content of 9%, was subjected to primary beneficiation by froth flotation technique using the naturally hydrophobic property of graphite as opposed to the associated impurities.
Abstract. 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 consists of quartz and graphite with minor quantity of mica. It analyzed 89.89% ash and 8.59% fixed carbon.
The physical separation (also known as beneficiation) typically involves several processes, such as mining, comminution, and flotation (Chelgani et al., 2016). In particular for graphite beneficiation, a multistage grinding and flotation process (can be up to 10 or more stages) is commonly employed (Peng et al., 2017, Peng et al., 2023).
