The flotation process takes advantage of the fact that Graphite is hydrophobic and tends to float on the surface. Flocculents and/or flotation agents are added to collect particles together and air is normally pumped in to create a froth that can be removed by skimming arms or paddles which helps reduce the amount of moisture in the material.

The flotation method of graphite ore is mainly based on the difference in wettability of the surface of graphite and gangue minerals. Due to the good hydrophobicity of graphite, it will adhere to and float on the air bubbles, while the hydrophilic gangue will remain in the water to achieve flotation separation. 1.

Froth flotation is a physico-chemical separation process. Separation is principally based on differences in surface hydrophobicity. However, particle size and density have a significant impact. Initial flotation patent and application was developed for graphite by the Bessel brothers (1877). Similar to graphite, coal is naturally hydrophobic.

Graphite is naturally floatable due to its hydrophobic property and also soft and smears on other gangue particles, rendering the gangue more or less floatable too. Due to this reason it is important to concentrate on areas such as suitable flotation reagents, depression agents, pH modifiers, and particle size to be fed during the process. The paper surveys and analyses the suitable particle ...
