The USe of ColUmn floTaTion for The reCovery of

G.m. Callow patented the first pneumatic flotation cell which used air sparging through a porous bottom and horizontal slurry flow in 1914. The first countercurrent column flotation device was designed and tested by Town and flynn in 1919. Cross-current pneumatic flotation machines were widely used in industry in 1920’s and

Multi-Stage Flotation for the Removal of Ash from Fine ...

Graphite ore collected from Hunan province south China was characterized by chemical analysis X-ray diffraction and optical microscopy. Rougher and multi-stage flotation tests using a mechanical flotation cell and a flotation column containing an additional centrifugal force field were carried out to promote its grade and economic value. In rougher flotation both the mechanical flotation ...

Flotation Circuit - an overview ScienceDirect Topics

Improved metallurgical performance of column cells in iron ore flotation is reported and attributed to froth washing which reduces the loss of fine iron minerals entrained into the froth phase Dobby 2002. The Brazilian iron ore industry has embraced the use of column flotation cells for reducing the silica content of iron concentrates.

Advances in Fine and Coarse Particle Flotation: Canadian ...

Jul 18 2013 Flotation works very well for particles that are typically in the range 20 to 150 μm in diameter for base metal ores. In this range it is possible to obtain quite high recoveries in conventional flotation machines. Outside this range the recoveries decline progressively whether it is with the very fine or thecoarse end of the size spectrum.

New directions in flotation machine design - ScienceDirect

Oct 01 2010 A new cell has been developed the Concorde Cell in which the pre-aerated feed is raised to supersonic velocities before passing into a high-shear zone in the flotation cell. The local dissipation rate is of the order of 100 kWm 3 one to two orders of magnitude higher than is available in conventional mechanical cells.
