An eddy current separator (ECS) is a machine that uses a powerful magnetic field to separate non-ferrous metals from an input waste or ore stream.
[2] In mining, ECS is sometimes used to separate metals from mined ore.[3] The eddy current separator is applied to a conveyor belt carrying a layer of mixed waste.
[4] Non-ferrous metals caught in the eddy current end up in a product bin, while other material falls off the belt due to gravity.
[4] U.S. patent 3,448,857A for a device using eddy currents to separate non-ferrous metals from non-metals was granted to William Benson and Thomas Falconer of Eriez Magnetics in 1969.
