The particle size to which the ore is ground depends on the nature of the ore. The grind must be fine enough to liberate the mineral grain from associated rock, but producing too small a particle size is both expensive and detrimental to recovery. Froth flotation is generally limited to size fractions between roughly 65 and 100 mesh.
The poor copper recovery of the fine particle size was contributed to a lower SE value of −20 μm size fraction as the slight changing trend of lead recovery with the particle size increased, ... Modelling the limits of fine particle flotation. Miner. Eng., 24 (2011), pp. 50-57. Google Scholar.
COARSE AND FINE PARTICLE FLOTATION. Mineral particle size is an important parameter in froth flotation.In 1931,Gaudin,et al.[1] showed that coarse and extremely fine particles are more difficult to recover by froth flotation as compared to intermediate size particles.This was approved by Morris[2]in 1952.Generally,the flotation recovery and efficiency deteriorate rapidly when operating in the ...

on its flotation was studied in a typical copper ore. A two-stage (Cu and pyrite) rougher flotation indicated that maximum Au recovery (95%) can only be achieved with pyrite flotation (recovery, 93%). A decrease in grind size of the flotation feed from 70 µm to 38 µm and without pyrite flotation stage

RECOVERY OF FINE-PARTICLE COAL 539 Baranov (21) also reported that nonionic agents such as aliphatic alcohols have little affect on the surface charge of oxidized coal. It has been shown that unoxidized coal is more easily recovered in typical flotation operations which use neutral, oily collectors (22, 23).The reduction

trends. In fact, coarse and extremely fine particles are more difficult to be recovered by the froth flotation compared with intermediate-size particles.[11,12] In various studies on copper flotation, it is noted that the maximum copper recovery can be achieved at the intermediate range with particle size of 50–70 µm.

pyrrhotite recovery in the environmental desulphurization process by flotation? Two main approaches are used to improve the fine particle recovery in flotation; to increase the particle size, or to decrease the bubble size. Particle size is increased through several aggregation methods and the aggregated particles are then floated, a
