Natural graphite ore can be easily purified by froth flotation due to its natural hydrophobicity [3,4,5,6]. Flake graphite exhibits a stronger hydrophobicity and is more floatable than amorphous graphite [7,8,9,10,11,12]. As illustrated in Figure 1, graphite beneficiation generally consists of a multistage grinding and flotation process [13,14].

Following the mineral processing beneficiation of a natural graphite mined ore to make a graphite concentrate, further purification can be done by chemical leaching. In conjunction with caustic and hydrochloric (HCl) leaching, hydrofluoric (HF) acid can be used for its ability to leach both the metallic impurities and the silica (quartz ...
On benefication of an indigenous graphite ore of Malakand, Pakistan, on laboratory and pilot plant scale by froth flotation technique, the ore, which initially contained 17% graphitic carbon, was upgraded to a graphite concentrate containing 84% graphitic carbon with more than 70% recovery.
The graphite beneficiation processes depend upon the nature and association of gangue minerals present in ore body. It can be enriched easily by flotation because of its natural hydrophobicity [3], [4], [5] .
Graphite electrodes (anodes and cathodes) can only be produced from natural graphite ores by several beneficiation processes, which include repeated crushing, milling, and flotation to separate the graphite flakes from their ore body.
For the flotation of graphite ore, two main costs are involved: the cost of ore material and the cost incurred in the beneficiation process. The costs involved in the beneficiation process includes plant maintenance, consumables, electricity supplies, utilities cost, cost of flotation reagents (collector, frother, and depressant), and cost of ...
