Low-intensity separators are used to treat ferromagnetic materials and some highly paramagnetic minerals. Minerals with ferromagnetic properties have high susceptibility at low applied field strengths and can therefore be concentrated in low intensity (<~0.3T) magnetic separators. For low-intensity drum separators used in the iron ore industry, …

1.2 Magnetic Susceptibility. In the magnetic systems of interest here, the magnetization M is usually proportional to the local value of H.If a magnetic field H of a certain intensity is applied to a substance, the intensity of the external magnetic field within that substance may be higher or lower than in the surrounding space. In the first case, …

where μ 0 is the permeability of free space and M is the volume magnetization. In the absence of an external magnetic medium, the H-field lines are identical to B-field lines outside a magnet (the stray field) and only differ by a factor μ 0, (B = μ 0 H); but inside they point in a different direction. B is solenoidal (∇⋅B = 0), meaning …
