DESIGN AND TEST OF A 7-T SPLIT-PAIR MAGNET FOR MAGNETIC SEPARATION

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