Magnetic Separation and Magnetic Properties of LowGrade ...
The grade of Mn for the roasted ore could only be concentrated to % with a recovery of %. Therefore, it is concluded that the lowgrade manganese ores with antiferromagnetic and paramagnetic (or diamagnetic, but not strongly ferromagnetic) properties could be efficiently beneficiated via highintensity magnetic separation.
