Basic Idea Flotation column cells are flotation act as three phase settlers where particles move downwards in a hindered settling environment counter-current to a flux of rising air bubbles that are generated by spargers located near the bottom of the cell. The sparger technology is an important design choice, and allows the user to optimize the performance based on the feed characteristics ...

Metso DR flotation machines are open type and incorporating a vertical circulation of pulp, similar to the action in a propeller agitator. Pulp from an intermediate zone of the cell is circulated down into the eye of the impeller, mixed with air, and diffused out over the entire bottom of the cell…
11.3.3 Flotation equipment. 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.
COLUMN FLOTATION CELLS. Key Features-1. There is no mechanical agitation/shear. The cell is relatively tall and narrow. Gas bubbles are generated by sparing. Froths are deeper, and wash water is applied to the surface of the froth. Industrial columns are 6-14 m in height and 0.5-5 m diameter.

Metso Microcel™ sparger consists of in-line static mixers and a centrifugal pump. Tailings slurry is pumped from the base of the columnthrough the static mixers, where air and slurry are mixed under high-shear conditions to create the bubble dispersion.
The dispersed air flotation (DiAF) process was utilized to separate algal cells (Chlorella sp.) from water. Two types of collector, cationic N-cetyl-N,N,N-trimethylammonium bromide (CTAB) and anionic sodium dodecylsulfate (SDS), were used. It was observed that 20% of cell removal was achieved in the presence of 40 mg/L of SDS, and ca. 86% of the cells were removed at 40 mg/L of CTAB.

May 01, 2007· By using the mechanical flotation cell the ash content of the same coal was reduced to 19.52% and 82.32% combustible recovery was obtained. 8. The results of column flotation tests are closer to those of the release analysis tests. In other words, column flotation is more efficient than mechanical flotation for fine coal cleaning.

Flotation is the most widely used beneficiation method for fine materials, and almost all ores can be separated by flotation. Another important application is to reduce ash in fine coal and to remove fine pyrite from coal. The flotation machine is mechanical equipment for realizing the froth flotation process and separating target minerals from ore.
