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).

Arif Bhatti et al. studied the beneficiation of low-grade graphite ore and indicated that low dosages of frother were enough for graphite flotation because of the natural floatability of graphite. Accordingly, 0.005 kg/t of MIBC and 1 kg/t of kerosene were concluded to be the appropriate dosages for the single-stage froth flotation of Kish ...
THE BENEFICIATION OF GRAPHITE BY FLOTATION USING A LOCALLY SOURCED COLLECTOR -SOYBEANS OIL ... shows that soya beans oil is a potential …
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.
A final graphite concentrate with 4.24% ash and 14.42% yield was obtained using the developed biocollector by flotation of low-grade graphite ore with 89.47% ash content.

The graphite used in battery anodes is typically a form of high-grade purified flake graphite, which has a layered structure that allows for the intercalation of lithium ions during charging and discharging cycles. Since graphite is naturally hydrophobic, flotation beneficiation is the most utilized enrichment technique for upgrading.
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 …
The underground graphite mines employ drilling and blasting to break up the hard rock which is then moved by mine cars pulled by a locomotive vehicles to the surface and then to the plant. Graphite is a natural floater. Flotation has become the accepted method of beneficiation of graphite (Crawford and Ralston, 2008).

With the severe depletion of coarse flake graphite (a critical raw material) resources, developing and utilizing fine and ultrafine graphite resources have recently attracted attention. Froth flotation is a widely used technique for the initial enrichment of graphite; however, the flotation selectivity decreases significantly along with particle …
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
By increasing the demand for flake graphite, the beneficiation of fine and ultrafine graphite ores (fine flake and aphanitic graphite) has been widely considered. 3−10 Flotation and chemical purification (leaching) are the main processes for upgrading graphite and its ash removal. 11,12 Prior to chemical purification, flotation separation is ...
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 …

In beneficiation of graphite by the method of flotation, it has been almost impossible to avoid the entrainment of gangues such as sericite into graphite concentrate. Hence, to solve the aforementioned problem, the use of Nigrosin (C 22 H 16 N 6 O 3 ) as a depressant for graphite in lead-zinc ore processing technology was introduced recently ...
Peng et al. [20] reported that a beneficiation process consisting of a rougher flotation, five stages of regrinding, and six stages of cleaner flotation produced a concentrate with 92.01% carbon content at the graphite recovery of 91.14%. Nevertheless, additional stages of flotation failed to obtain a concentrate with 95% carbon content.
Flake graphite has good flotation, so froth flotation is an effective beneficiation method. Large flake graphite has excellent properties and wide application. In the beneficiation process, we should protect the surface of large flake graphite from damage and separate it in time. Therefore, we use the method of a multi-stage grinding …
