Froth flotation process - American Cyanamid Company

Froth flotation is a commonly employed process for concentrating minerals from ores. In a flotation process, the ore is crushed and wet ground to obtain a pulp. A frothing agent, usually employed with a collecting agent, is added to the ore to assist in separating valuable minerals from the undesired or gangue portions of the ore in subsequent ...

Common Questions About Froth Flotation Process

2019-4-17  Froth flotation is the use of the physical and chemical properties of the surface of the ore, the use of chemical separation of useful ore. In the process of froth flotation, useful minerals are separated by floating them in the foams, and the way of keeping gangue minerals in the pulp is called positive flotation, while the way of floating gangue minerals in the foam is called reverse flotation.>

Celanese - The chemistry inside innovation

Flotation – A flotation frother – like Methyl Isobutyl Carbinol, 2-Ethyl Hexanol, or terpenic oil – and a “slurry” of fine powder and water are then introduced to a water bath (i.e., flotation cell) which is aerated, creating bubbles. Frothing – A stable froth is formed on the surface of the flotation cell from the aeration.

Froth flotation cell - level measurement VEGA

On the other hand, froth that is too thick indicates that the reaction time of the chemicals is too long. This has the consequence that too little of the medium gets processed. A density-compensated level measurement is the reliable solution in this process: this ensures that the density of the liquid remains constant and optimizes the process ...
