Froth Flotation - Metallurgist & Mineral Processing …

A run-away is a frightening experience for a novice flotation operator. Froth begins to flow from the surface of the cells at such a rate that launder water sprays cannot break down the froth and it then begins to overflow the launder depositing on the sump floor. Even by dropping the cell level the froth continues to flow and cannot be stopped.

Froth Flotation Cells by Parnaby Cyclones

Fine coal can be separated from shale and other waste by using a process including froth flotation cells. The coal is made water repellent by the addition of a reagent such as oil so that when a suspension of coal is agitated with air it sticks to the air bubbles and floats to the surface collecting as froth.

Effect of microemulsified collector on froth flotation of …

Froth flotation is a fine particle separation process based on the difference in surface hydrophobicity of different components. It is often very effective for coal cleaning since coal is naturally hydrophobic and minerals are generally hydrophilic. Because of coal’s hydrophobicity froth flotation has employed mostly non-polar

TECHNICAL NOTES 9 FLOTATION - Mineral Tech

Particles enter the froth phase when a bubble carrying the particles crosses the pulp-froth interface. The froth phase floats on top of the pulp phase and is formed by the bubbles that break through the surface of the pulp phase. The water in the flotation cell is conditioned to promote the formation of a more or less stable froth.
