From the WEMCO multi-cell rectangular-shaped mechanically-driven rotor/stator design.The primary difference from a mineral processing flotation cell is that the flotation chamber is fully encapsulated to prevent hydrocarbon vapor release into the atmosphere.
Froth flotation cells then aggressively bubble air through the slurry.The air bubbles attach to the hydrophobic particles in the slurry and float them to the surface creating a mineral froth at the top of the flotation cell.This concentrated mineral froth is then collected from the surface of the flotation cell.
Froth flotation is a common method to extract a certain type of mineral from ore while depressing the amount of undesired minerals in the extracted concentrate.It is done by adding certain chemical reagents to selectively rendering the desired mineral hydrophobic.In a flotation cell, air bubbles then lifts the mineral.
