The first corrective reaction is to raise the pulp level or add air to the cells to quickly increase the overflow. As a band aid solution this is correct, but as the ultimate correction it is not. The purpose of the air is to provide the medium that the collector attaches and to provide a surface for the mineral to be floated away on.

no flotation can occur. Contact between particles and bubbles can be accomplished in a flotation cell such as the one shown schematically in Figure 5. Figure 5: Simplified schematic of a conventional flotation cell. The rotor draws slurry through the stator and expels it to the sides, creating a suction that draws air down the shaft of the stator.

Flotation Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry. The particle size for mineral being recovered is generally less than <0.1mm.
Flotation takes place within flotation cells which broadly include mechanical, column, jet, film and novel flotation cells. Research in flotation cells is 'themed' into research into conventional mechanical flotation cells and novel flotation cells. These two areas have a common 'cross-cutting research theme' of investigating particle ...
The control of pulp levels in flotation cells is a complex control task. Many different aspects such as cell structure and valve sizing, and their effects on control, have to be taken into account.
Flotation equipment is a kind of beneficiation equipment which takes bubbles as the carrier and uses the difference in mineral surface wettability to separate minerals. In the late nineteenth century, flotation as a beneficiation method was explicitly proposed, and various types of flotation equipment were developed, including flotation …
