Flotation kinetics of a pyritic gold ore ScienceDirect

Jan 17, 2011· Research Highlights Flotation kinetics of a pyritic gold ore was studied with respect to particle size. Gold recovery increased by 4% with grinding from a P 80 of 205 microns to 53 microns. Second order kinetics is a much better representation of semi-batch flotation. The first order flotation rate constant is independent of particle size in this range. The second order flotation rate constant

Effect of particles size range on iron ore flotation

The results in Figure 2 illustrate the effect of the presence of ultrafine particles in iron ore flotation, therefore justifying the necessity for desliming. The high levels of Si0 2 in concentrate in the case of the high ultrafine contents can be justified by the high consumption of collector by the ultrafine particles, caused by their high

7 Factors Affecting Froth Flotation Process JXSC Machine

1 Grinding Particle Size. Both large ore particles (larger than 0.1mm) and small ore particles (less than 0.006mm) affect flotation efficiency and mineral recovery. In the case of flotation coarse particles, due to the heavyweight, it is not easy to suspend in the flotation machine, and the chance of collision with the bubbles is reduced.
