mineral flotation cell christoartfair.nl

A flotation cell is a reactor in which the three phases solid, liquid, and gas, interact to separate valuable minerals that contain saleable metals, and waste minerals called gangue. In the case of mineral flotation, the solid is the ground rock particles, the liquid is water, and the gas is usually air.

1 Froth Flotation Fundamental Principles

Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.

Froth flotation

For froth flotation, the ground ore is mixed with water to form a slurry and the desired mineral is rendered hydrophobic by the addition of a surfactant or collector chemical (although some mineral surfaces are naturally hydrophobic, requiring little or no addition of collector). The particular chemical depends on the nature of the mineral to be recovered and, perhaps, the natures of those that are not
