magnetic separation of minerals

Magnetic separation takes advantage of differences in the magnetic properties of minerals. Minerals fall into one of three magnetic properties: ferromagnetic, paramagnetic and diamagnetic. Ferromagnetic minerals are themselves magnetic (i.e., magnetite and pyrrhotite) and can be easily separated from other minerals with a magnet since they will stick to the poles of the magnet

    Magnetic separation of minerals is a topic that is seldom reported in the literature for two reasons. First, separation data generally are byproducts of other projects; and second, this study requires a large amount of patience and is unusually tedious. Indeed, we suspect that most minerals probably are never investigated for this property

    II. Magnetic Separation Magnetic separation of mineral particles depends on the magnetic susceptibility of the minerals to be separated. This is a complex phenomenon which is a function of chemical composition, especially minor amounts of iron or manganese, and atomic-lattice structure. The simplest form of magnetic separation is by hand

    magnetic separators and the principal ferromagnetic mineral separated is magnetite (Fe304),although hematite (re203) and siderite (FeCO3) can be roasted to produce magnetite and hence give good separation. The removal of tramp iron from ores can also be regarded as a form of low-intensity magnetic separation

    Sep 02, 2021 The magnetic separator is the key beneficiation equipment for separating magnetic minerals from non-magnetic minerals or minerals with magnetic differences. The process is based on the different components in the separated materials, which means that in the working magnetic field, the different magnetic field forces and other forces received by

    Although in low-gradient magnetic separation, the field gradient is generally less than 100 T m −1, the field gradient in high-gradient magnetic separation can be increased to thousands of T m −1 by introducing a magnetizable matrix (such as a steel wire mesh, steel balls, grooved plates or steel wool) into the magnetic field [25,35], as
