Froth Flotation

Froth Flotation Froth flotation is a surface chemistry based separation process which is extensively used in the processing of mineral ore deposits as a method of separating the desired mineral component from their associated gangue material [17,34]...

How Froth Flotation Works

Froth Flotation Charles Kubach, Mine-EngineerCom The process of froth flotation is generally described as a physical-chemical action, where a mineral particle is attracted to, and attaches itself to the surface of a bubble, and is transported to the surface of a cell, where it overflows into a discharge launder, usually with the assistance of paddles, rotating in the direction of the launder ....

Flotation Froth

The last step in the flotation process is creating a strong but short-lived froth by adding frother when the bubbles reach the surface of the slurry This froth prevents bursting of the bubbles and release of the Cu mineral particles back into the slurry...
