Flotation Feed - an overview ScienceDirect Topics

Flotation impellers would be expected to follow a similar equation, although a slightly different constant may be found. The circulation rates are very high. For example, a 14.2 m 3 cell with an impeller of diameter 0.84 m, rotating at 114 rpm, would have an internal circulation of 51 m 3 per minute, thus circulating the cell contents between three and four times a minute.
