mechanical flotation cell

[mi′kan·ə·kəl flō′tā·shən ‚sel]
(mining engineering)
A device that separates minerals from ore water pulp; it consists of a cell in which the pulp is kept mixed and moving by an impeller at the bottom of the cell; the impeller pulls air down the standpipe and disperses it as bubbles through the pulp; the floatable minerals concentrate in the froth above, and the pulp is removed by a scraper.

Grau and Heiskanen (2005) had previously found that the size distribution in a number of types of mechanical flotation cell was well-described by a so-called 'upper limit distribution', also referred to as a three-parameter log-normal distribution, given by Mugele and Evans (1951).
Grainger-Allen (1970) observed that air cavities formed at the rear face of impeller blades in laboratory mechanical flotation cells.
