This series of products has an ul- tra-high background magnetic field that cannot be achieved by ordinary electromagnetic equipment, and can effectively separate weakly magnetic substances in fine-grained minerals.It is suitable for beneficiation of rare met- als, non-ferrous metals and non-metal- lic ores, such as cobalt ore enrichment, impurity …
The dry magnetic separator is used for sorting dry magnetic minerals, and is mainly used for selecting large-sized, coarse-grained ferromagnetic ores and fine-grained weak magnetic ores. It has three types of single disc (diameter φ = 900 mm), double disc (φ = 576 mm) and three discs (φ = 600 mm). The magnetic field strength can reach 880 …
Low-intensity magnetic separation (LIMS) tailings are a common by-product obtained after magnetite magnetic separation, containing hematite and the rare earth minerals monazite and bastnaesite. Due to the weak magnetism of hematite and rare earth minerals, magnetic separation has low efficiency.
1. Introduction. High gradient magnetic separation (HGMS) has been witnessed wide application in processing weakly magnetic minerals [1], [2], [3], [4].In most cases, HGMS is applied in the roughing separation stage and subsequent separation processes such as gravity separation [5], flotation [6], [7] or magnetic roasting followed …
Generally speaking, the choice of magnetic separator is as follows: strong magnetic separators select weak magnetic minerals, and weak magnetic separators select weak magnetic minerals. With the development of magnetic separation technology, the boundary between weak magnetic minerals and non-magnetic …

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 …
