Coarse and Fine Particle Flotation Recovery

In The Days of gravity concentration, the art of ore dressing developed on the cardinal principle of saving the values at as coarse a size as possible. Flowsheets were designed which featured an alternation of crushing and concentrating operations. Thus an ore might be crushed to ½ inch, jigged to yield a finished concentrate and a middling; the latter being recrushed to ¼ inch, jigged a

Dec 01, 2017· 1. Introduction. Flotation is regarded as one of the most important techniques for the separation of minerals, especially for the finely disseminated ores, where fine grind is essential to achieve the liberation of the value minerals from the gangue (Bagster and Mcllvenny, 1985, Sivamohan, 1990, Song and Lu, 1994).The flotation process of fine particles is plagued with losses of recovery

Flotation taking its coarse

However, the adoption of coarse particle flotation technology may also carry some drawbacks. Debbie Laney, mining chemicals technical sales manager at Chevron Phillips Chemical Co, says: "For instance, during the flotation process, the recovery of both fine and coarse particles is lower than the recovery of middle-sized fractions.

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.

Effect of Coarse Particles in Mineral Flotation AusIMM

Flotation behaviour can be controlled, due to diminishment of granula quality and extension of specific surface area, by adding coarse particles (high- grade concentrates) to condition pulp. It has been substantiated that coarse particles can intensify fine particle flotation and its mechanisms are effects of carrier, intermedium and assistant aggregation of coarse particles.
