• Induced Gas Flotation

    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 - an overview | ScienceDirect Topics

    Gas Flotation Separation. In onshore applications, initial separation of oil from the unwanted solids present when the oil is produced is often accomplished by a gravity process. However, oil and solid particles are often so small that they distribute themselves evenly in the water phase and will not settle readily by gravity alone.
