Grinding particle size. During the flotation process, the flotation effect of too coarse ore particles (greater than 0.1mm) and extremely fine ore particles (less than 0.006mm) is not good, and the recovery rate is low. 1. In the coarse flotation, due to the large weight, the shedding force of the ore particles increases.

Nov 9, 2020Aeration The reason why gold ore leaching requires aeration is that effective oxidation helps dissolve gold, so proper aeration can increase the solubility of oxygen in the ore slurry, thereby increasing the rate of gold dissolution. It can usually be achieved by aerating or stirring the slurry.
