In this regard, the physics of magnetic separation at the microscale is not unlike that of gravitational sedimentation, or sedimentation in a centrifugal field, in that the range of separation is bounded at the small particle size limit by the randomizing effect of thermal motion, and also strongly depends on the separation-specific property of the …Web

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 …Web
