Beneficiation of an iron ore fines by magnetization roasting and
Enhancing the magnetism saturation and magnetic susceptibility means that an effective magnetic separation can be achieved. A high grade concentrate containing 65.4 wt% iron with an iron recovery of 92.7% was achieved by magnetic separation with a grinding fineness of 85 wt% passing 38 μm. The results demonstrated that the application of ...

Concentration of Ore – Definition, Methods of Separation, Examples
To separate the ore and gangue, magnetic characteristics of either the ore or the gangue are used. The ore is first finely processed before being conveyed on a conveyor belt that passes over a magnetic roller. The magnetic ore stays on the belt, while the gangue slides off. By eliminating non-magnetic impurities, this process is utilised to ...
