Column Flotation • Theory and Practice

conventional mechanical cells. Column flotation, invented in the early sixties, proved to be a better alternative to the conventional cells. The main advantages of column flotation are : i) improved recovery, ii) higher grade, iii) lower capital and operating costs, iv) less wear and tear due to absence of moving parts and v) requirement of less floor space. Columns of varying design are in ...

Flotation Cell - an overview ScienceDirect Topics

Column cells have been developed over the past 30 years as an alternative to mechanically agitated flotation cells. 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 ...

Flotation columns first appeared on the market in the late 1960’s as an innovation in the field of froth flotation. Columns offered a solution, or at least an improvement, with respect to some of the problems encountered with conventional flotation cells. The most evident was the higher length-to-diameter ratio, which can be visualized as a series of vertically stacked cells. This geometry ...
