Magnetic separation has been used since 1955 for processing a variety of minerals from iron ore in steel production to the desulphurisation of coal. The accumulation of such fines and slimes during mining operations and the increasing global demand for quality products motivated the use of the semi-continuous pilot wet high intensity magnetic separator (WHIMS) introduced in 2008.

In this study, the method based on direct reduction and wet-magnetic separation was found to possess a strong degree of flexibility to raw material. Using pyrite as the optimal additive and a magnetite concentrate (Fe 3 O 4 content 89.59%) as the raw ore, a RIP was produced. We investigated the effects of varying different experimental

Processing of taconite consists of crushing and grinding the ore to liberate iron-bearing particles, concentrating the ore by separating the particles from the waste material (gangue), and pelletizing the iron ore concentrate. A simplified flow diagram of these processing steps is shown in Figure 11.23-1.

This machine uses magnetism produced by permanent magnet to adsorb strong mags in the slurry. With the help of magnetic field and flushing water, it realizes the separation of mags and non-mags. The magnetic minerals pass onto the concentrate collecting tank in the process of rotating, and the non-mags end up with tailings.
