In dry beneficiation of coal, coal and mineral matter are separated based on differences in their physical properties such as density, shape, size, luster, magnetic susceptibilities, frictional coefficient, and electrical conductivity [23–25]. Dry beneficiation gives a clean coal as well as reduces some of the polluting elements associated ...

And beneficiation allow the utilization of the inorganic and heavy minerals associated with oil shale. Oil shale beneficiation by froth flotation hasn't received enough attention in the last two decades. The main reason was the cost of the process since flotation requires extensive grinding to liberate oil shale kerogen. However, the recent

Fig. 1, Fig. 2, Fig. 3 present the size distributions of the singly-ground test minerals at various grind times. For each of the test minerals and grinding periods, the Gaudin–Schuhmann distribution modulus (α) is obtained from the slope of the linear portion of the distribution curve, and the size modulus (X m) is obtained by extrapolating the linear portion of the curve to the …

In the flotation process, coarse stage grinding minimizes the grinding cost and formation of slimes. In the majority of cases, a grind size (K80) of approximately 200 microns is sufficient for flotation. After primary grinding, mica, if present in an appreciable amount, should be floated to minimize interference with spodumene flotation.
