Induced-air flotation cell | FL

Flotation is about creating the proper energy dissipation rate in the cells to obtain optimal contact between the air bubbles and the particles for extracting the minerals. The function of the rotor/stator is to make bubbles from the induced air, suspend the particles, and create an environment for bubbles and particles to make contact and rise ...

Efficient flotation Cell Level Control

Flotation cells are mechanical equipment that bring the ore in contact with air, water, and chemical agents. Their main function is to separate the previously conditioned slurry into a concentrate and tailings. The level of these cells is controlled by dart valves, which in turn are operated by actuators.The calculation of the level control …

Improving flotation energy efficiency by optimizing cell hydrodynamics

3.4. Effect of cell hydrodynamics on flotation performance. Overall recovery (R O) in a flotation cell is a function of recovery in the collection (R C) and froth (R f) phase, Eq. (4), ( Dobby, 1984 ): (4) R o = R f R c R f R c + 1 - R C. The drivers of recovery are very different in these two phases.

Flotation Reagents

In practical operation the function of promoters may be considered two-fold: namely, to collect and select.
