DESIGN AND PERFORMANCE ASPECTS OF COAL FLOTATION ...FROTH WASHING A flotation technology that has froth washing capabilities has advantages over those that do not, as froth washing is one of the most effective methods employed to reduce entrainment thereby enabling concentrates with the lowest ash content to be produced. The amount of washwater used is therefore an important process variable so the system must be able to be operated over the ...

The solution is brought to a temperature around 50°C Celsius, after which air bubbles are blown into the tank. The air bubbles lift ink particles to the surface of the suspension and form a froth that is then removed.

Froth_flotationFroth 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) ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement.
