However, the beneficiation of graphite ore is pivotal as it accounts for the quality, market price and suitability for various technological applications including energy storage in lithium-ion batteries. Since graphite is spontaneously hydrophobic (like coal) in nature, flotation is the common and apt technique for beneficiation of graphite ore.

It's a matter of how you design grinding and classification process before the flotation. If there is overgrinding problem in the process you will have graphite slime coating on clay particles and this makes those clay particles behave like graphite particles and will report to the floated products. I suggest: 1.

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 ore was crushed in stages followed …

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).
