1 Froth Flotation Fundamental Principles

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.

Pdf Cfd Model Of A Selfaerating Flotation Cell

The effect of impeller speed on the air flow in a selfaerated Denver laboratory flotation cell was investigated using computational modelling. Air is induced into the slurry by the impellers rotating action. The rate of air flow is determined by the suction pressure created by the impeller, the hydrostatic head of the slurry and the frictional losses along the delivery shaft from the inlet ...

Pulp Amp Paper Selecta Flot Deinking Flotation

AND FLOTATION CELLS The pulp suspension is pumped through the multi-injectors into the flotation cells. These newly de-veloped multi-injectors of the next generation mini-mize the pressure drop in the injector, hence reducing the energy demand. Inside the patented injectors, the pressure energy is used to suck air into the feed stock.

Pdf Level Control Strategies For Flotation Cells

Flotation is a difficult process to run efficiently. One way to make flotation performance better is to improve cell level control. However, controlling pulp levels in flotation cells is a complex control task because of strong interactions between the levels in flotation cells. Therefore advanced controllers are needed to give good level control.

Technical Notes 9 Flotation

Almost all successful models of the flotation process have been based on the premise that flotation is a kinetic process. In this way a model can be formulated in terms of a rate of flotation which can be quantified in terms of some of the many chemical and physical factors that define the environment inside a flotation cell.
