摘要： An eddy current separator (10, 10a, 10b, 10c, 10d, 10e, 10f, 10g) and a separation method for separating non-ferromagnetic particles (14) by engaging the particles to force the particles into a primary magnetic field (34) to increase the induced eddy current flow that generates particle magnetic fields such that subsequent release of the particles allows increased magnetic field propulsion to propel the particles distances that vary according to their electrical resistance, densities, shapes and sizes. Different embodiments move the particles into the primary magnetic field by an inclined engagement member (42) that may be a flexible member (42') or a brush (42''), a vertically movable roll (54a), a rotary brush (54b), an upper auxiliary conveyor (64), an upper belt reach (26) of a belt conveyor (16), a vibratory member (26') of a vibratory conveyor (16'), and an inclined gravity slide (70) that may be a curved trough (72).
