    Aug 01, Another problem is that the majority of material held in tailings dams is fine grained, lt 50 m 11 Fine particle flotation There are several challenges in the flotation of fine particles, generally those less than 50 m in size Firstly, the probability of bubble particle attachment occurring is low (Miettinen et al, 2010)02/06/2016· Coarse VS Fine Flotation It is a very natural assumption upon the part of many people that, the finer the particles are, the easier it is to float them This assumption has rested on two grounds: Finer particles in a given ore are more extensively liberated Finer particles weigh less, therefore are more easily supported by flotation’s balloons—the air bubbles AlthoughCoarse and Fine Particle Flotation Recovery

  • DE9A1 Method for removing fine material

    The method involves removing 20 percent mineral fine material by flotation in a flotation plant (4) The consistency of a fibrous material suspension (S) before the flotation amounts to 1 to 3 percent, particularly 15 to 2 percent The accepted material (A4) of the flotation plant is put in a wash device of a laundryAlso, mines don’t have to worry about storing tailings that are very fine and unstable — the material can be easily dewatered — and you can reduce conventional flotation capacity as well “It depends upon the ore and its density but, for copper, which we’re really focusing on, you get an acceptable recovery in conventional flotation up to about 120 or 130 microns Certainly, itFlotation: The Past, Present and Future of Mineral
