ALUMINUM RECOVERY FROM ELECTRONIC SCRAP BY HIGH-FORCE(R) EDDY-CURRENTSEPARATORS

The amount of electronic scrap which contains a substantial portion of non-ferrous metals, primarily copper and aluminum, has been growing. The present study is directed toward aluminum recovery by a newly deve loped eddy current separator. The investigation on shredded personal c omputer and printed circuit board scrap demonstrates that the High-For ce(R) eddy-current separator will be applicable for this purpose. It h as been shown that, by a single pass of the materials on the High-Forc e(R) eddy-current separator, an aluminum concentrate out of personal c omputer scrap can be obtained with a purity of 85%, while maintaining a recovery in excess of 90%, with the feed rate being up to 0.3 kg/min .
