This article focuses on DuPont’s goal to produce a low-cost, reliable, easy-to-maintain high-temperature superconductivity (HTS) magnetic separator that will meet the commercial needs of remote ore processing operations. DuPont’s superconductivity business is finishing the detailed design of a pilot separator for processing kaolin clay and titanium dioxide ore. The separator will incorporate the largest high-temperature superconductivity magnet, in terms of combined size, magnetic field, and stored energy, that has ever been built. The 0.8-m-dianleter magnet will deliver a 2.5 tesla magnetic field and store 800 kilojoules of energy. DuPont is addressing the strength issues with a mechanical support structure that reinforces and supports the windings and does double duty as part of the conduction cooling process.
