TECHNICAL NOTES 9 FLOTATION - Mineral Tech

The LTM-2 probe sends a pulp level signal that is utilized by the flotation cell level control system to maintain pulp level depth at setpoint. Actual pulp level measurement is in the set range below the froth lip height. At the bottom of the bracket is a 40 mm polypropylene bushing to hold the bottom end of the probe steady as well as ...

Level control strategies for flotation cells

Level measurement of a flotation cell is not as straightforward as it first sounds because we actually measure the depth of the froth. Of interest in a flotation cell is how deep the froth is above the slurry, as this determines the grade of the resulting concentrate. The typical range for a froth depth is 600 mm from the top of the flotation ...

flotation cell, and then to a 3 m3 flotation test rig with magnetite/silica slurry and air, to collect turbulence data. An orthogonal experimental design was used for both sets of tests, with different impeller speeds, air flow rates, cell level (aspect ratio) and sugar concentration (viscosity) as input hydrodynamic parameters. From the

FloLevel Technologies, a process automation developer based in Australia, has introduced a new self-cleaning acoustic level and flow analyzer for flotation cells. This new technology, according to the company, accurately measures pulp/slurry interface and froth height, as well as froth density and froth flow rate, to provide valuable process ...

Novel control for froth flotation cells

To work efficiently, flotation cells depend on continuous froth formation. If the froth layer is too thin, it cannot transport the sufficient amount of dispersed or suspended particles to the surface. On the other hand, froth that is too thick indicates that the reaction time of the chemicals is too long.

DESIGN AND PERFORMANCE ASPECTS OF COAL FLOTATION ...

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 ...

Floatation cell level control

Flotation is a complex process that is affected by a multitude of factors. These factors may be inherent in the circuit design, or in how the flotation plant is operated. The FloatStar suite of control modules utilises advanced process control to overcome design-related limitations and maximise circuit performance during operation.

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 | ore dressing | Britannica

Flotation cells require precise control of compressed air because the frothing process efficiency is based on the speed of the froth as it moves from the surface of the slurry to the recovery area. The speed of the froth is controlled by the air bubbles induced into the flotation cell, tank level and reagent dosages.
