Abstract
The present invention provides a method for obtaining a cobalt-enriched material, comprising: (a) providing a discharged lithium ion cell comprising cobalt; (b) crushing the cell to form fragments; (c) separating the fragments to obtain particles of between 63 µm and 1 mm in size; and (d) treating the obtained particles with a magnetic field of between 3000 and 5000 Gauss, so as to select cobalt-enriched material from non-cobalt-enriched material, wherein the method does not comprise a heat treatment, as well as a product obtained from the method, and an apparatus for carrying out the method.
