Abstract
The separations achieved by eight conventional cyclone washers have been evaluated to determine their performance when processing intermediate size coal of 28-mesh bottom size. The dense-medium cyclones provided efficient, sharp separations in treating feeds of up to 44 percent of near-gravity material at separating specific gravities ranging from 1.42 to 1.55 (One separation of a secondary feed was made at 1.63). Complete washability analyses are shown by sizes of the composite feed to these cyclones. The magnetite losses per ton of coal processed ranged from 0.6 to 2.0 Pounds; however, of the eight plants reporting losses, seven indicated magnetite losses were 1.1 Pounds or less per ton of coal processed.
