Well pine oil is used in froth flotation process because it does not have affinity towards water because of the hydrophobic chemicals as its cconstituentsand it attracts impurities which can be washed away.

The main ingredients of the froth flotation are the Collectors and Froth Stabilizers. Collectors pine oils, fatty acids etc increase the wettability of the metal part of the ore and allows it to form a froth and Froth Stabilizers cresols, aniline etc sustain the froth. The oil wets the metal and the water wets the gangue. Paddles and air

Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity.Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents.

Through consecutive froth flotation, non ferrous metals can be further separated. The separation efficiency is 93%. Although operating process waters run in closed circuits, the use of ferrosilicon requires excessive wastewater treatment, which renders this process too expensive in the long run.
