Coal Flotation Technical Review - ACARP

Column flotation is expected to require more reagents on account of the much larger bubble surface available. This was found to be true, with frother consumption about double the rates used in conventional flotation. Experience so far shows that this can be expected to be substantially reduced as operating accumulates and new reagents may be ...

New concept in flotation column design SpringerLink

A form of column flotation cell is described in which the contact between the feed and the air stream is made in a mixing device at the top of a vertical downcomer. The air-liquid mixture flows downward to discharge into a shallow pool of pulp in the bottom of a short cylindrical column. The bubbles disengage and rise to the top of the column to overflow into a concentrate launder, while the ...
