Superconducting high gradient magnetic separator

Results are reported from studies examining the applicability of a superconducting high-gradient magnetic separator to the extraction of uranium from seawater. Factors affecting the efficiency of separation such as shape of the filter cross section, diameter, diameter of separated particles, susceptibility, and external field were examined. In the tests two types of stainless-steel filaments of 30- and 100- mu m diameter were prepared and inserted into a matrix of CuO and Fe/sub 2/O/sub 3/ particles. It was found possible to separate the particles selectively according to susceptibility.<
