1. Introduction. The gravity and dense medium separation processes are widely used for beneficiating coarse coal particles (+500 μm), while the froth flotation is the most efficient process for cleaning fine coal (−500 μm) (Laskowski, 2001).Flotation columns are superior to conventional mechanical cells in cleaning fine coal because of having a deeper froth as well as a froth washing ...

Flotation Depressants Mineral Processing Metallurgy

First let’s change the amount of the Flotation Depressants used. The valuable mineral that isn’t liberated from the unwanted mineral will begin to be depressed along with the waste. For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted mineral’s color. This is because the froth is becoming purer as ...

Flotation | ore dressing | Britannica

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process.

Flotation Froth an overview | ScienceDirect Topics

Froth flotation is a process that selectively separates materials based upon whether they are water repelling (hydrophobic) or have an affinity for water (hydrophilic). Importantly, the word flotation is also used in the literature to describe the process in density separation in which lighter microplastics float to the surface of a salt solution.
