Optimization of Air-injection Spargers for Column Flotation Applications
Column flotation cells have become the most popular separation device designed for industrial applications requiring the concentration of wanted or unwanted mineral from the rest material in a pulp. To achieve separation, an air sparging device is required to produce bubbles in the flotation cell. In column flotation operations sparging

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.
