This cell separation technique utilizes the potential to label cell surface markers with magnetic beadtagged antibodies and the ability of a magnetic field to migrate the labeled particles from a distance. 1 This controlled migration by a magnetic force magnetophoresis is invaluable in separating heterogeneous cell populations and is the basis for magnetic-activated cell sorting MACS.
A method of separating wrought and cast aluminum from a scrap mixture containing the two is disclosed. In this method, the scrap mixture is first heated to a temperature above the solidus temperature of the cast aluminum scrap. At this temperature, the scrap mixture is crushed thereby causing the cast aluminum to fragmentize into small pieces while merely causing flattening of the

Current magnetic separation technologies either employ a magnet attached to the side of a small tube, or a small tube with a magnetizable mesh inside. In the latter case, when a magnetic field is applied, the mesh becomes magnetized, trapping the particletarget components. However, there are significant limitations to both of these approaches.
