    coal and the relative minerals during flotation. The floatability of coal has been found to depend on both the pH and the precipitation of dissolved inorganic species Celik and Somasundaran, 1986; Liu et al., 1994a). Also, the natural hy-drophobicity of pyrite has been shown to be very much dependent on pH Koca-bag et al., 1990).

  • Coal cleaning by froth flotation

    mineral matter from low rank coal more selectively than macro-bubbles could. When a micro-bubble flotation technique was employed to float Appalachian coal, it produced a cleaner coal product than conventional macro-bubble flotation. A general kinetic model was proposed to represent the rate of flo­ tation of coal.

  • The behaviour of mineral matter in fine coal flotation ...

     · In coal flotation, the recovery of mineral matter may be attributed to two mechanisms: entrainment between air bubbles transported to the concentrate through pulp and froth phases and entrapment in aggregates of coal particles. In this study, saline water increased combustible recovery but also ash recovery compared to de-ionised water.
