    Arnold and Aplan (1986a) investigated the effect of clay type on coal flotation and indied that different clays influenced coal flotation differently. They suggested that for this reason, slimes in a froth flotation system should be well characterized. Kaolinite and illite clays were found to cause little or no coal .

  • Coal Washing |

    Coal Washing |

    Coal washing is accomplished by one of two major processes, by density separation or by froth flotation. Both processes depend on the fact that the particles of which a coal sample are made have different densities. When water, for example, is added to the sample, particles sink to various depths depending on their densities.

    A Brief Review of Pulp and Froth Rheology in Mineral Flotation

    In mineral flotation, rheological problems have limited the efficient upgrading of lowgrade and complex ores. Since pulp and froth rheology are deemed to play different roles in influencing the separation performance, in this paper, a brief review on pulp and froth rheology in flotation is provided, with an objective of developing a basic understanding of rheology in flotation.
