The feasibility of low-frequency ultrasound in enhancing the flotability of flaky graphite from low-grade graphite ore was investigated in this present study. This study involves a fundamental understanding of ultrasonic-assisted graphite flotation process and its relative comparison with the conventional flotation process.
In a typical process of enormous large flaky graphite ores, a multistage grinding-flotation process is employed to prevent large flakes from being destroyed …
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.
The flotation process of GO mainly includes the slurry mixing and dosing in the preparation stage and the flotation separation process. The multi-stage grinding of graphite ore before flotation can dissociate the gangue minerals that are associated or mixed in GO. Then the mineral particles that meet the flotation conditions are …

The operation of the process is affected by the mineralogical character of the ore, the grade of feed, the kind and quantity of flotation agent and, to a less extent, by the temperature of the pulp, the place and method of adding the flotation agent, the type of flotation machine used, and the method of removing concentrate.
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 (d 80: 186 μm) followed by rougher flotation in Denver flotation cell using diesel as collector and pine oil as frother yielded a rougher concentrate.
