A low-grade graphite ore (run-of-mine, R.O.M) from Tamil Nadu, India, was utilized in this study for recovery of graphite by flotation. The R.O.M graphite ore was size reduced in stages in a laboratory jaw crusher and a representative sample was drawn by riffle sampling.

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.

The conventional graphite flotation process flowsheet is made up of a traditional jaw crusher, cone crusher, ball mill, rod mill, and mechanical flotation cells.
