  • Coal maceral separation using column flotation

    4/1/1996· Prior to maceral concentration using column flotation, a liberation study found that the particle size corresponding to 80% liberation of each maceral group was found to be smallest for liptinite. The 80% liberation particle sizes for the liptinite, vitrinite, and inertinite macerals were 4,

    Modified column flotation of mineral particles. Jorge Rubio. IntroductionColumn flotation is today a subject of great interest in mineral processing with steadily growing research and industrial application (Finch and Dobby, 1990;Dobby and Finch, 1991;Agar, 1991). Major advantages of columns include low capital and operating costs, better

    Flotation columns work on the same basic principle as mechanical flotation cells mineral separation takes place in an agitated and/or aerated water mineral slurry where the surfaces of selected minerals are made hydrophobic (water-repellent) by conditioning with selective flotation reagents. However, in column flotation, there is no mechanical mechanism causing agitation.

    Working principle of cyclonic-static micro-bubble flotation column Flotation is an essential fine mineral particles separation technology. Since the flotation column was invented in the mid-1960s, many kinds of flotation columns have sprung up since 1980s (Zhao et al., 2016; Harbort and Clarke, 2017). Among these flotation columns, the cyclonic-static micro-bubble flotation column (FCSMC)

    Key Words : Column flotation, Theory & practice, Applications. INTRODUCTION Separation of valuable minerals from gangue is far from ideal in conventional mechanical cells. Column flotation, invented in the early sixties, proved to be a better alternative to the conventional cells. The main advantages of column flotation are : i) improved recovery,
