Basic Principles Variables Affecting Froth Flotation

Mar 12, 2016  In the agitation-froth process, it is, in general, more economical to attain enhanced bubble precipitation by greater intensity and duration of agitation than by heating the pulp, and in bubble-column processes difficulties in dispersion of the oil are surmounted by adding the oil to the grinding mills, or using an oil easy to disperse.

How Froth Flotation Works - Mineral Processing Metallurgy

Aug 08, 2015  How Froth Flotation Works. To start with I will give you a simplified description of how selective froth flotation works, lets start over again with a description of the equipment and why it works. When the grinding circuit is finished with the ore it will be ground very fine and the density of the slurry will be between 30% to 45% solids.

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