A method and apparatus are disclosed for the microbubble flotation separation of very fine particles, especially coal, so as to produce a high purity and large recovery efficiently.
The effectiveness and efficacy of flotation diminishes with the size of the particles. However, the kaolin industry is unique in successfully using flotation with fine particle size feed.
Apr 19, 1994· This invention relates to the froth flotation of fine particles and in particular to the recovery of coal from an aqueous slurry of coal fines also containing associated impurities as suspended fine solids by froth flotation, and to the beneficiation of fine mineral particles by froth flotation.
In froth flotation, adsorption is a strong consequence of surface energy, since the small particles have a high surface area to size ratio, resulting in higher energy surfaces to form attractions with adsorbates.
The flotation feed cycles past an airjet first, where it encounters the high energy useful for attaching fine particles to bubbles. "That's like the Jameson Cell, actually," he said. Then it flows into a fluidized bed, where the lower-energy environment allows coarse particles to attach.
