The disclosed eddy-current separator has several new features. One includes a magnet assembly which is metal-sleeved for protecting the magnets from impact by particles or objects piercing the waste-carrying conveyor belt with which the separator is used. A low-rotating-speed epoxy-layered shell surrounds the sleeve for additional protection. A conveying extension carries ferrous "fines" from the conveyor into the receptacle used to collect waste from which non-ferrous material has been separated. Such extension permits such fines to be under the substantial influence of the magnet assembly over an arc well less than 180.degree.. The conveyor belt uses relatively-closely-spaced cleats of reduced height to reduce the "loading" of an individual cleat with potentially-piercing ferrous fines. A two pole magnet assembly may be used and/or a magnet assembly in which the magnet pole faces are curved for air gap reduction.
