Large Particle Flotation in Shallow Air Cell
The flotation of large particle coal has also been tested with the shallow air flotation machine. Coal as large as minus ½ plus 3/8 inch with a specific gravity of 1.39 was floated with the shallow air cell; this is as large as is considered theoretically possible to float.

Effect of Coarse Particles in Mineral Flotation - …
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.

Coarse PartiCle Flotation
PARTICLE FLOTATION Developed in 1999 and later patented in 2002, Eriez was the first in fluidized-bed flotation. This coarse particle recovery system has the ability to capture particles up to and exceeding 2 mm. Having reshaped the industrial minerals market, the HydroFloat® is now being applied to the sulphide and base metal markets
water treatment – floatability and rising velocity ...
Flotation is said to be induced when the particle’s density, originally greater than that of the liquid, is artificially reduced in order to ensure its flotation. This process takes advantage of the capacity of some solid (or liquid) particles for uniting with gas bubbles (usually air or nitrogen) in order to form "particle-gas" pairs that are less dense than the liquid of which they ...
The upgrading of rare earth oxides from iron-oxide ...
1-12-2018 · The flotation response of the rare earth oxides (REO) and major gangue phases was investigated using sodium oleate and hydroxamic acid as collectors; and sodium silicate and starch as depressants. Generally, sodium oleate displayed relatively better selectivity for REO than hydroxamic acid in the presence of the depressants.
