They use a set of water sprays to wash the coarse coal as it passes across the screening media. A wet-drum magnetic separator is then used to recover the magnetite from the slurry that flows from the drain-and-rinse screens. While magnetite losses are often blamed on the magnetic separator, they could be occurring in another area.
