coal beneficiation flotation process

The hard coal beneficiation process in mechanical preparation plants generates coarse, small or fines rejects andcoal tailings slurries. The tailings are the finest grain size, with the majority below ~ 0.25 mm, whereby material sized below 0.035 mm makes up to 60% share in the slurry composition.
