According to the size of the magnetic susceptibility, the magnetism of minerals can be divided into ferromagnetism and paramagnetism. Ferromagnetic: When there is a strong interaction between atoms or ions with magnetic distance, under a certain temperature and without external magnetic field, their magnetic distance shows a directional ordered arrangement in a certain area, that is, they have the property of spontaneous magnetization, so the magnetic susceptibility is large. PTMS Electromagnetic Separator can be used for iron removal process.
Few minerals are ferromagnetic, such as magnetite, pyrrhotite, etc., which all have a high positive susceptibility value, generally more than a few thousand. Paramagnetism: minerals in the PTMS Electromagnetic Separator external magnetic field, the induced magnetism is slightly larger, the direction of magnetization and the direction of the external magnetic field is the same, the magnetic rate is not large, is positive, is the attraction of the magnetic field.
It is usually caused by the presence of trace amounts of transition metals in the mineral composition. These minerals are abundant and cannot be attracted by permanent magnets, but can be attracted by strong PTMS Electromagnetic Separator electromagnets. Such as hornblende, tourmaline, pyroxene, etc.
