Abstract
The invention relates to an equipment and method for flotating mineral slurry (4) in a flotation cell provided with a flotation mechanism (3), comprising at least a drive shaft (6), a rotor (5) and a stator (7), and at least one inlet (11) for feeding mineral slurry (4), a froth launder system (8) for removing mineral enriched froth, at least two discharge outlets (28, 12) for removing two material flows with two different grain sizes from the flotation cell, in which case the flotation cell (2) is provided with a classifying equipment (1) including means for setting the mineral slurry (24) to be classified, separated from the mineral slurry, in an essentially upwardly moving rotary motion in the flotation cell, as well as means for separating coarser material (25) from finely divided material (26).
