Water Handbook

Quartz sand, silica sand, anthracite coal, garnet, magnetite, and other materials may be used as filtration media. Silica sand and anthracite are the most commonly used types. When silica is not suitable (e.g., in filters following a hot process softener where the treated water is intended for boiler feed), anthracite is usually used.

Magnetite Uses

Using magnets, magnetite can be easily recovered from the waste and coal streams and then re-used in the coal separation circuit. Recyling the magnetite provides a cost saving to the operator, and is an environmentally conscious method of utilizing this valuable resource.

Abstract: Magnetite, slurried in water, is used to create an apparent heavy medium in which fine coal (0.1 to 2.4 mm) is cleaned of its mineral impurities. The magnetite is much finer in size (1 to 44 μm) than the coal and is usually recovered from the coal and refuse by magnetic drum separators.

Various red shades of hematite were prepared by the calcinations of the precipitated goethite at temperatures ranging from 600 to 900 C. Maghemite was obtained by thermal treatment of magnetite at 200 C.
