An investigation of the flotation mechanism in the aerosol column flotation machine
Russian Journal of Non-Ferrous Metals, 2009It is shown that the induction time decreases as the temperature decreases if there is air bubble adhesion to hydrophobic and hydrophilic particles; if there isn’t, the time decreases where hydrophobic particles stick to one another and increases in the case of adhesion of hydrophilic particles.

BGRIMM Pneumatic Mechanical Agitation Flotation Machine
2021With the changes in mineral resource endowments, especially the increasing proportion of low-grade ores, large pneumatic flotation machines have been developed rapidly and become the most widely applied flotation machines. There are many kinds of non-ferrous, ferrous and non-metallic minerals in China, but the resource grades are not high, and the ...

Publisher Summary Separation of minerals by flotation involves selective concentration of hydrophobic minerals in the froth. The selectivity is based on wettability differences of the treated minerals with only hydrophobic particles being able to attach to bubbles. The process is accomplished in a flotation cell. The necessary conditions in the cells

Aeration characteristics of laboratory flotation machine impellers
International Journal of Mineral Processing, 1977Abstract The aeration characteristics of several laboratory flotation machine impellers have been studied paying special attention to the pressure generated by impeller rotation. Correlations have been established between pressure (or Euler) number and Reynolds number, pressure ratio and air flow number, and these correlations have been compared with

Hydrodynamic design of self-aerating flotation machines
Minerals Engineering, 2000This paper reviews the hydrodynamic design of self-aerating flotation machines. The important criteria relating to mixing, solids suspension, air transfer, and power are discussed. Data are presented for all the standard sizes of WEMCO brand machines, showing the continuing use of hydrodynamic criteria in the design of those machines.

Effects of Stator Configurations on the Flotation Performance of Induced Gas Flotation Machine
Volume 7: Fluids Engineering, 2016Induced Gas Flotation (IGF) vessel is used for water treatment of plant industries such as oil sand and chemical plants. An understanding of the interaction between the stator and rotor is essential for the design of IGF with consideration of geometric blade configuration is essential for the design of IGF.

Multiphase models of flotation machine behaviour
International Journal of Mineral Processing, 1978Abstract Models in which the cell contents are partitioned into distinct pulp and froth phases are reviewed critically. The nature of the mixing within the phases is discussed. Multiphase models describing froth column concentration gradients and pulp residence time effects are mentioned.

The Effect of Operating Parameters on Flotation Dynamics of BF-40 Flotation Machine
Applied Mechanics and Materials, 2014BF type flotation machine is a kind of self-air & slurry suction flotation machine. In this paper, several key flotation kinetic parameters of BF-40 flotation machine are introduced, and the relationships of impeller rotating speed, impeller immersion depth, air suction amount, power consumption and air dispersion are studied by water test.
