Mineral Flotation - International Mining
Flotation cell hydrodynamics (gas dispersion parameters) is critical to the performance of the cell. When we talk about these parameters, we are talking about measuring what is happening in a flotation cell. Flotation is really about making bubbles and using the surface area of the bubble to do the work of transporting hydrophobic minerals to ...

Flotation cells | SKF | SKF
Increase uptime and ease the maintenance burden. Separating minerals in a froth flotation cell has a particularly corrosive effect on a slowly rotating rake and its components. Mixtures of slurry, surfactant, water, air and froth can quickly lead to failed seals and bearings. Which, of course, means costly unplanned downtime and lost productivity.

Flotation Cell Control - International Mining
Flotation cells have three main control parameters (1) reagent dosing rate (2) froth depth and (3) air addition rate. Many other parameters may vary such as feed rate, particle size distribution and head grade, however these are the output of upstream processes and are not controlled in the flotation circuit itself.
