The magnetism of a mineral is usually expressed in terms of its magnetic susceptibility. The value of the magnetic coefficient of most minerals (weak magnetic) is certain, and the magnetic coefficient of only a few minerals (strong magnetic minerals) changes with the shape, size and magnetic field of the ore particles. Mineral production by PTMS magnetic separator divides minerals into 3 categories, depending on their specific magnetization (magnetization of minerals per unit mass) :
(1) Strong magnetic minerals: such as magnetite, titanium magnetite, zinc iron spinel, pyrrhotite and so on.
(2) Weak magnetic minerals: such as hematite, pseudophematite, limonite, siderite, ilmenite, hydromanganese, hard manganese, biotite, pyroxene and so on. PTMS magnetic separator can remove the iron (FE2O3) inside.
(3) Non-magnetic minerals: such as calcite, quartz, feldspar, chalcopyrite, galena, sphalerite, pyrite, etc.
Magnetite is partially or completely transformed into pseudoparhematite after oxidation (the crystalline shape is the same as magnetite, and the chemical composition is hematite). With the increase of the oxidation degree of magnetite, the mineral magnetism decreases. The molecular formula of magnetite is Fe3O4 (or Fe2O3·FeO), and that of hematite is Fe2O3. Therefore, with the change of magnetite oxidation degree, the content of FeO also changes. PTMS magnetic separator can remove the iron (FE2O3) inside.
