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 ...

Keywords: magnetic separator; permanent magnet; dry presorting; iron ore; review 1. Introduction Dry magnetic separation is a technology that sorts magnetic minerals from gangue using air as the medium instead of water. When raw ore is fed to the magnetic separator, the magnetic particles are subjected to magnetic force due to the nonuniform ...

Magnetic separation has been applied in ore processing to separate magnetic materials, such as iron oxides, from the bulk of nonmagnetic minerals with smaller specific densities . This approach separates particles by passing finely ground ore particles through a magnetic field at different intensities.

Wet Magnetic Separator. Wet magnetic separator is a magnetic separator commonly used in iron ore dressing plants. It can be used not only for sorting operations, but also for replacing the magnetic dewatering tank as a concentration device before filtration. The process is more complicated, and it is necessary to rely on water as the medium for ...
