Froth flotation takes place in a water-mineral suspension. It is used for selectively separating minerals by taking advantage of differences in their hydrophobicity. The surfaces of the graphite particles are hydrophobic (water-repellent) and it is thus very amenable to flotation in water using suitable/selective conditioning reagents.
