Popis: | Dispersiveness of emulsion composed of oily reagents is estimated using the method of laser diffraction in experimental and in-process tests of flotation of slurry coal. Effect of agitation level in emulsification on emulsion dispersiveness and on flotation of different size coal of two grades is described. It is found that emulsification of oily reagents has influence on flotation efficiency. Increased dispersiveness of thermal gasoil and waste motor oil emulsion exerts a beneficial influence on flotation of coarse and fine coal of the both grades while flotation quality with waste motor oil emulsion worsens. It is possible that selectivity of separation of coarse and less hydrophobic coal also decreases. |
