Minerals | Special Issue : Recent Advances in Flotation Process
Dear Colleagues, It is well-known that froth flotation has been one of the most important methods for separating different minerals based on the difference in their wettability in relation to appropriate circuit design, optimization, and dynamic process control as well as the true selection of reagent type, particle size, pH, etc.
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.
