EVALUATION OF FROTHER PERFORMANCE IN COAL FLOTATION.

Separation efficiency in flotation depends, to a considerable extent, on the efficiency of the frother used. A successful frother must achieve a delie balance between froth stability and nonpersistency. Ideally, the frother is not supposed to influence the state of the surface of the coal and minerals. In practice, however, interaction does occur between the frother, other reagents, and ...

Froth Floation | Hoffman Lamson Solutions

Froth flotation, also called ore flotation when used in mining appliions, is a method for physically separating particles by having air bubbles that selectively adhere to specific surfaces. The particles with attached air bubbles are carried to the surface and removed. Froth flotation is one of the most widely used methods for ore beneficiation.

Improving The Performance Of Froth In Coal Flotation Using ...

Therefore, correct froth stability is of utmost importance in flotation. Despite the importance of froth stability, many coal flotation plants encounter overly stable froth problems especially when saline water is used. For example, at a fine coal flotation plant in Queensland, overfrothing occurs due to the formation of stable froth.
