ABSTRACT:
Ores containing mineral values are separated into two slurries, one having primarily fine particles and gangue and the other having primarily coarse particles. The slurry having fine particles and gangue is adjusted to a solids content of less than about 15 percent, as necessary, and then conditioned by the addition of appropriate promoter reagents, a flotation collector, and a froth modifier. The gangue, containing a disproportionate share of impurities, is floated in a column flotation cell wherein the fine particulates are not mechanically agitated, and removed. The remaining fine particulate underflow, containing a disproportionate share of the minearl values, is then processed directly, or combined with the slurry containing the coarse particulate to yield a flow having reduced impurity content and increased recovery of the mineral values.
