Flotation Cell
The use of power ultrasound in mining. L. Gaete-Garretón, in Power Ultrasonics, 2015 35.5.1 The flotation process. One of the most used processes to concentrate mineral from a mine is flotation. To perform a flotation process the mineral is finely ground (particle sizes between 50 and 150 μm), then the ground mineral is mixed with water in a container called a flotation cell.
Flotation cell
The primary difference in flotation cells is the two ways of introducing the gas. Gas introduced into the bottom of a cell and dispersed into a water in the form of very fine bubbles will rise to the top of that cell and carry with it suspended solids and entrained oil. Additional frothing can be created by injecting surfactants or other water ...
