    Abstract

    This paper describes the horizontal defl ection behavior of particles in paramagnetic fl uids under a highgradient superconducting magnetic fi eld. Movements of single particle were observed experimentally and indicated that they could be defl ected to different positions. Based on these results, the behavior of groups of particles from ore samples was examined in the superconducting magnetic. It was found that these particles could be defl ected and settled at a certain position due to the combination of gravity and magneto-Archimedes forces as well as a lateral buoyancy (displacement) force. Mineral particles with different susceptibilities and/or densities could be defl ected to different positions, thus producing groupings of similar types of particles. The work described here, although in its infancy, could form the basis of new approach to separating particles based on a combination of susceptibility and density.
