A system and a method for separating and recycling magnets made from rare earth elements from an article of manufacture used an alignment device to property position the rare earth magnet for processing. Once proper alignment is made, a separating device removes the magnet and a portion of the article. A heating device demagnetizes the magnets and vibration causes the magnets to separate from the portion of the article. Electromagnets remove the portion of the article and the rare earth magnets pass through for reclamation.

The invention relates to a magnetic separator for the dry separation of material particles having different magnetic susceptibilities, wherein a rotatable cylinder that comprises a stationary magnetic device arranged therein, and extending essentially across its length, is disposed. A sorting chamber is furthermore provided for which extends along at least a portion of the outer surface of the cylinder in the circumferential direction of the cylinder and parallel to the longitudinal axis of the cylinder. The magnetic separator according to the invention features means for the dispersed output of material particles into the sorting chamber, as well as means for generating a stream of conveying air in the sorting chamber. A motor for rotating the cylinder around its longitudinal axis, wherein, during operation, the outer surface of the cylinder is moved by the rotation of the cylinder in a direction essentially perpendicular to the direction of the stream of conveying air is, moreover, provided for.

A tiered magnet modular collar designed to catch metallic objects inside a garbage disposal. The tiered magnet modular collar includes a plurality of tiered magnets, each tiered magnet having a first elongated member offset from a second elongated member. The first elongated member is atop a second elongated member via a connecting bar. The first elongated member has a first distal end opposite a first proximal end with a first interior surface opposite a first exterior surface. The second elongated member has a second distal end opposite a second proximal end with a second interior surface opposite a second exterior surface. The first elongated member and second elongated member have an arcuate shape such that the tiered magnets affix to one another in an annular manner. In this way, a user is able to affix the tiered magnet modular collar around a garbage disposal to catch metallic objects inserted therein.

A device for separating weakly magnetic first particles, for example hematite particles, from mixture (912) comprising the first particles (913) and less magnetic second particles (914) is presented. The device comprises first magnetizing equipment (901) for producing magnetic field and for moving the mixture so that mutually opposite polarity portions (N, S) of the magnetic field sweep the mixture in a sweeping direction and thereby deflect the direction of movement of the first particles towards the sweeping direction and away from the direction of movement of the second particles. The device comprises also a supply equipment (932) for supplying the mixture to the carrier equipment with the aid of gravitation and a second magnetizing equipment (931) connected to a feed box (920) for producing second magnetic field for deflecting a direction of movement of the first particles differently than a direction of movement of the second particles when the mixture is moved by the gravitation towards the carrier equipment so as to generate, to the mixture arriving at the carrier equipment, a concentration gradient of the first particles. The pre-concentration of the first particles simplifies their separation form the mixture.
