Abstract

A 160 mm bore, 7 T split-pair magnet was constructed and tested aiming at mineral processing through HGMS (high gradient magnetic separation) or HCMS (helical channel magnetic separation). This work describes the design and test results of the pair of coils operating under current in parallel mode. In the case of the antiparallel current mode, a large repulsive force between coils is generated and a strong magnetic field gradient outside the magnet is created. A continuous magnetic separation system made with a helical channel magnetic separator for application in TiO₂ processing is analysed
