Magnetic separation is the only effective way of separating the valuable components of iron ore from the diamagnetic inclusions so far as the extractable iron compounds have a high magnetic susceptibility (as a rule, 20 90·107 m3/kg8). In mining industry the technology of preliminary minerals concentration with selfpropelled
Dwari et al. (2013) used a combination of dry and wet magnetic separation methods to upgrade a lowgrade siliceous iron ore with magnetite, hematite, and goethite as major iron minerals. The study showed that for particles finer than 200 µm, the separation methods produced a magnetic concentrate with 67% iron and iron recovery of 90%.
Magnetic separation technology plays an important role in upgrading such lowgrade iron ores, because the magnetic separation process possesses the combined advantages of large capacity and low operating cost, as well as being environmentally friendly.
Magnetic separation is often considered pertinent for manganese ore beneficiation when the ore is abundant with siliceous rich gangue mineral phases. However, the process is deemed to be inapposite for the ferruginous type of ore, and remains a grey area of research. In the present investigation, two different types of manganese ore were studied in detail to understand the influence of ...
In the case of magnetic separation, such as for iron minerals, there are several crushing and grinding stages with the tailings passing through a froth flotation process (Schreiber et al., 2021).
