Economic factors affecting coal preparation: plant design .

The desliming step increased the net tonnage to 923 t/h, a net gain of 24 t/h over the base scenario (Case A). This represents nearly 6.5 million annually of additional revenues (24 t/h × 6000 h/year × 45/ton = 6.48 MM/year). Obviously, desliming to reject high-ash, high-moisture material is very attractive for this particular coal.

Desliming Cyclones - 911metallurgist

Analysis of the feed to several plants revealed that the material finer than 44 µm (325 mesh) and even 70 µm (200 mesh) was usually very high in ash content (>30 %) with a considerable amount of superfine size clays. Due to the high ash content and the poor dewatering ability of the minus 44 µm coal when recovered, it became viable to consider completely discarding this size fraction.
