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, …

In many iron ore mines, wet high-intensity magnetic separation is being preferred in the concentration of low-grade hematite ores to avoid the flotation methods. The other important factor is the selection of magnetic separator which can capture the hydroxyl-bearing iron minerals such as goethite and limonite that are feebly magnetic. …

These separators can be applied in both wet and dry modes. On the other hand, high-intensity magnetic separators can be utilized to treat weakly magnetic materials, whether fine or coarse, in dry or wet mode. In the case of fine, feebly magnetic minerals, the best choice for magnetic separation is high-gradient magnetic …
