Grinding For Froth Flotation

If they are subjected to flotation soon after grinding they will tend to stick to bubbles and to be raised to a froth. Silica and gangue are wetted by water and will tend to sink. The natural differentiation of valuable mineral from gangue in this way is very good but the sticking of sulfide minerals to air bubbles can be improved by the addition of a collector to the water phase.

Froth Flotation Wikipedia

Froth Flotation Wikipedia

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 wanted.
