1 Froth Flotation Fundamental Principles

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.no flotation can occur.

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.Almost all successful models of the flotation process have been based on the premise that flotation is a kinetic process. In this way a model can be formulated in terms of a rate of flotation which can be quantified in terms of some of the many chemical and physical factors that define the environment inside a flotation cell.Project duration 1 January 2021 31 December 2023 Objective RFC-Upscaling proposes the Reflux Flotation Cell RFC technology for mineral processing companies, with ROI in 3 4 years.
