| 摘要 |
The invention provides a method of controlling operation of a froth flotation cell, the method comprising: introducing gas into a liquid in the cell, thereby to create a froth on the surface of the liquid, the froth having a depth from the surface of the liquid to an overflow point at which the froth overflows and leaves the cell; and controlling the froth depth to optimise the gas recovery with respect to the froth depth. Optimisation of the gas recovery with respect to the froth depth leads to the recovery of a froth concentrate of both high grade and high product recovery.
