Coal beneficiation: theory and practice
Typical results in a coal beneficiation plant using spirals to treat fine coal indicated very little deterioration in performance with the under-slimed and deslimed feed material (−500 mesh) even when the feed contained ~50% of −500 mesh material. However, the clean coal ash reduced when the −500 mesh material was removed.
