Industrial application of column flotation began in earnest in the early 1980's, and is now accepted as a conventional application. For example, most of the world's major copper producers use column flotation as the final stage of cleaning. In addition, the technology is common for final cleaning of zinc, lead and molybdenum

The name "flotation column" implies that the vertical dimension is larger than the horizontal. "Counter-current" means that the direction of flow for the pulp and for the air bubbles inside the column is opposite each other. Three types of flotation columns are available commercially at present: (a) the Canadian ...
The column flotation technology is a new mineral beneficiation method developed on strong scientific principles for processing of fine low grade ores and minerals. The merits of the technology includes improved metallurgical performance in terms of grade and recovery, effective cleaning of froths, small foot print, low capital investment, less ...
The rougher fluorite flotation column was 18 ft high; the other three columns (cleaner fluorite, and mica and beryl rougher flotation columns) were 12 ft high. Each column was composed of flanged sections with 1.125-in-diam ports located at 1-ft intervals along its length.
Here is a classic Flotation Column Design with air spargers, froth launders and wash water header/tub. Column Flotation Cells make great "grade machines" but are know as weak on recovery. Low energy, low recoveries at each end of the size particle spectrum.

A brief review of the art of column flotation technology is presented. The flotation column characteristics are described, followed by an analysis of the principal variables involved in the process and the impact they have on column performance. Discussion is given of both industrial experience and fundamental studies. Attempts to model and scale-up flotation columns are …
In this investigation, the fine-grained bauxite ore flotation was conducted in a plate-packed flotation column. This paper evaluated the effects of packing-plates on recovering fine bauxite particles and revealed the fundamental mechanisms. Bubble coalescence and break-up behaviors in the packed and unpacked flotation columns were characterized by combining …
Flotation is an extremely size sensitive process and because the RC drilling process imparts a lot of energy into the sample, the resulting fine particle size distribution is likely to be much finer than required. Also, the detergents used in RC drilling will very often react unfavorably in the flotation cell with other reagents.

History of the flotation column can not be considered in isolation from the development of flotation apparatus on the whole. It can be argued that the first attempt to switch from oil flotation to the use of bubbles during flotation was performed Bessel brothers in 1877 (Berlin patent 42 class 22, July 2) and in 1886 (Berlin patent 39,369 May 12).
