The flotation machine is mainly used to separate non-ferrous metals such as copper, zinc, lead, nickel, gold and so on. It can also be used for the rough selection and selection of ferrous metals and non-metals. There are many structural forms of flotation machines. The most commonly used flotation concentrator is mechanical agitated flotationDarabi et al.

Engineering Aspects of Flotation in the Minerals Industry: Flotation

Spada M., Flotation Cell Agitair No.120, Revue Ind. Minerale, 52, p. 179, 1970. Google Scholar Bateman E. L., Agitair: Developments of Flotation machines, South African Institute of Mining and Metallurgy Colloquim, Recent Advances in the Design and performance of Flotation Equipment, March 1975. Google ScholarThe processing of low grade mineral ores using large scale flotation cells is obviously more advantageous than smaller-scale processing. Large-scale flotation cells have become increasingly important for effective volume scale-up. In this study, the latest and largest flotation cell in China, with an effective volume of 680 m3, is considered. Minerals Free Full-Text Hydrodynamic and Flotation Kinetic

WEMCO Smart Cell™ flotation machine. The Smart Cell flotation machine is a kind of mechanical agitation flotation machine improved on the basis of WEMCO1+1 flotation machine. As the impeller rotates, ambient air is sucked in via the vertical pipe, dispersed into fine bubbles through the disperser cover and uniformly When stopping at full tank, the steps are relatively simple. Stop feeding the ore first, then stop the stirring tank according to the flow direction of slurry, and stop the flotation machine backward successively from the first tank of the flotation machine. 3.

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.The cells are bottom driven. The principle advantage of the bottom driven flotation machine is the presentation of a flotation cell surface, and hence improved flotation test reproducibility for technicians with a moderate skill level.
