increasing their unit mass magnetic moment and specific
susceptibility, and effectively separating them from non-
magnetic minerals. From a technological and equipment
point of view, the application of HMPT technology to the
processing of BOLIO ores is feasible and offers an innova-
tive approach to the recovery of such polymetallic refrac-
tory iron ores.
