Column Flotation Cells
Column flotation cells, like mechanical cells, are used to perform mineral separations. Column cells do not use mechanical agitation (impellers). Instead, mixing is achieved by the turbulence provided by the rising bubbles. Columns are mostly used to produce final grade concentrates because they are capable of high selectivity.
Design of Flotation Cells and Circuits
Until only a few years ago mechanical flotation machine capacity was limited to eight to 15 tons of ore per running foot per 24 hours, and this meant that a "small" 10,000 TPD mill needed in the neighborhood of 150 rougher cells, while a 30,000-ton mill would need about 500 rougher cells. With the same units the mill of tomorrow would …

How to Operate a Flotation Circuit
One jam an operator always seems to get into sooner or later, however, is this matter of oil or grease in the pulp. A case is on record where a man cleaned the black grease from under the big gear on a ball mill and tossed the goo into the flotation feed launder to get rid of it. The result was a cross between a bubble bath and the Johnstown …
