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 Reagent
The flotation process begins as soon as collector is introduced along with air bubbles in the flotation cell. In other words, the collector has no time for conditioning coal slurry. As shown in Fig. 14, the flotation agents do not have to be present on the surface of coal particles but coated on the surface of the bubbles, which is suitable ...
