    2014-11-1 · The coarse coal sample (CoalB) was obtained from a BHP BMA coal plant. The sample was screened with the −710 μm fraction being the flotation feed.Mineral compositions are shown in Table 1 with about 7.4% clay minerals such as kaolinite, smectite, and illite. The combustible matter content is about 83% in the flotation feed.

    2016-6-2 · Flotation was the powerful new tool to which all refractory ores would respond. Time, however, has shown that flotation is no cure-all, and there are poor as well as good ways of applying it. Coarse VS Fine Flotation. It is a very natural assumption upon the part of many people that, the finer the particles are, the easier it is to float them.
