4.5. Dry Magnetic Separation . The magnetic separation of aluminous Mn-ore revealed nearly similar results as that of the ferruginous Mn-ore. The bulk considered as feed contained about 23% Mn and 16% Fe. When different size fractions were processed at different magnetic intensities the results obtained at 1.0 tesla represented the best results.

Concentrating Hematitic Limonitic Iron Ores by High Intensity
However hematitic limonitic and sideritic iron ores with lower magnetic susceptibility require concentration methods other than low-intensity magnetic separation. The ore sample was first of all crushed below 10 mm for easiness of operation with Permroll. The crushed sample was then fed to Permroll without any classifi ion.

Magnetic separation separates mineral particles based on their ‘permeability’ to magnetic fields. Some materials can react quite differently when they are exposed to a magnetic field. The degree of reaction is dependent on a number of factors such as the atomic and molecular structure of the material and the net magnetic field associated
