Minerals Cisa have developed Visiofroth - a system which calculates parameters of the froth surface using vision from remote cameras mounted about individual flotation cells. The parameters calculated from this system can be utilised within process control strategies to achieve stabilisation or optimisation of the flotation process._x000D_ As part of a JKMRC AMIRA P9 …

In the flotation process, surfactants (so-called collector in mineral processing) are of paramount importance in regulating the surface properties of minerals and achieving effective separation [16].Fatty acid surfactants, known for their cost-effectiveness and high performance, are commonly used in hematite flotation [17].Nan et al. used α-bromohydric acid (α-BLA) to …

It is possible to increase the rise rate of the formed flotation aggregates, and thereby enhance the efficiency of flotation treatment via secondary saturation of the flotation cell with d b = 0.1-0.3 mm air bubbles. The air bubbles of 0.02-0.07 mm diameter float up in laminar flow regime but create light turbulence in the flotation cell.

As observed by Moys (1979), the introduction of a froth baffle has a notable effect on the overall performance of a flotation system.Froth baffles were inserted in the froth with their bottom section just below the pulp-froth interface (2–5 mm).Its positioning would impose little changes to the pulp phase sub-processes, thus it can be assumed that any change to the …
