Removal of Sulfate Ions by Precipitation and Flotation

ABSTRACT. The removal of sulfate ions from natural waters, as well as from industrial effluents of different origins, is a problem, considering that most of the proposed processes are inefficient and have a high cost, mainly when reducing the sulfate ion concentration to values below 500 mg.L-1 is required. The flotation technique, combined with precipitation, has proven to be efficient for ...

Froth Flotation

2016-12-19 · 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.

What is the principle of floatation

2021-11-22 · The principle of floatation states that when an object floats on a liquid the buoyant force that acts on the object is equal to the weight of the object. Following are the pointers to remember in floatation: The displaced volume of fluid is equal to the volume of the object which is immersed in the fluid. If the weight of the object is greater ...
