Froth flotation - Howling Pixel

Froth Flotation - Howling Pixel

principle of operation. before froth flotation can work, the ore to be treated is reduced to fine particles by crushing and grinding (a process known as comminution) so that the various minerals exist as physically separate grains.this process is known as liberation.the particle sizes are typically less than 0.1 mm (100 µm), but sometimes sizes smaller than 7–10 µm are required.

in dissolved-air flotation, the air supply rate is 810 g air/m3 raw water, or about 0.007 m3 air/m3 water, which means three orders of magnitude smaller than the previous case (29). therefore, it seems to be desirable to be able to produce large numbers of small bubbles by mechanical means, but so far this appears to be beyond the present technology in large scale.
