Magnetite Beneficiation: A Focus on Flowsheet Configuration

27/08/2020  tragedies have motivated research into the dry processing of iron ores. In the mineral processing industry, dry magnetic separation is commonly used for removing tramp metals [10] and the coarse cobbing of magnetite ores [11,12]. However, it is ine cient for processing finely ground magnetite ores [7,10]. This is because conventional dry magnetic separators are e ective

Davis Tube Tester - 911 Metallurgist

The separator consists of an inclined tube 25 mm in diameter, placed between pole-tips of an electromagnet. Material to lie separated is passed through the tube; the strongly magnetic fraction is held by the magnetic field while the weakly magnetic material is washed down the tube. It was suggested that a magnetic induction of 0.1 T or greater between the magnet poles should be used. However ...
