Flotation Cell - an overview | ScienceDirect Topics

The major operating difference between column and mechanical cells is the lack of agitation in column cells that reduces energy and maintenance costs. Also, it has been reported that the cost of installing a column flotation circuit is approximately 25–40% less than an equivalent mechanical flotation circuit (Murdock et al., 1991).

Flotation columns getting the most from fine ores -

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.
