Creating a Froth for Flotation. Important to the flotation process is controlling the surface tension of the interface among the bubbles, the aqueous solution, and the hydrophobed particles. This is achieved by a combination of the design of the flotation machine (called a flotation cell) and the use of a second class of surfactants known as frothers.

Optimization of flotation separation using interfacial chemical methods. Foaming agents are added to the liquid as part of this process. The hydrophobic particles accumulate in the foam layer on the surface where they are skimmed off. The investigation of the definitive interfacial processes and the foaming process falls within the proficiency of our measuring instruments.

Froth flotation

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.

Answers. Best Answer: Froth Flotation is a selective process for separating minerals from gangue by using surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) orebodies economically feasible. The flotation process is used for the separation of a large range of sulfides,
