Flotation Cell - an overview ScienceDirect Topics

Flotation columns, as they came to be known, were “invented” back in the 1960s in Canada [35]. The main feature that differentiates the column from the mechanical flotation cell (of Denver type) is wash water, added at the top of the froth.

Flotation columns getting the most from fine ores - ...

2017-10-16  In direct flotation, columns have been used mainly for cleaner stages due to their capacity for generating high-grade froths with fine material. The most common configuration involves a rougher with mechanical cells and a cleaner with columns, after regrinding the intermediate concentrates. This type of flowsheet aims at minimizing grinding costs.
