Magnetite Recovery in Coal Washing by High Gradient

High values of magnetite recovery were achieved at reasonably high material throughput rates with little coal found reporting to the magnetics. A single-stage separator incorporating a new matrix design was used at rates up to 4.4 tons of solids per hour per square foot of matrix cross-section (300 gpm/ft2).

Magnetite Wikipedia

Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of
