    Magnetic separation takes advantage of the differences in magnetic properties of minerals. Most minerals fall into one of these categories: ferromagnetic, paramagnetic, and diamagnetic. Among these categories, ferromagnetic materials show the highest magnetic susceptibility, hence they can be easily separated by the magnetic separation method

    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

    Magnetic Separation. Magnetic separators exploit the difference in magnetic properties between the ore minerals and are used to separate either valuable minerals from non-magnetic gangue, e.g. magnetite from quartz, or magnetic contaminants or other valuable minerals from the non-magnetic values. An example of this is the tin-bearing mineral

    Oct 13, 2021 The separation of feebly magnetic minerals in a state of fine division is a more difficult problem, as the capacity of the separator is cut down by the thinness of the ore layer which may be treated. In dry crushing plants the several crushing and separating machines are usually housed in, and the flying dust removed from within the casings by

Magnetite is the most magnetic of all the naturally occurring minerals on earth, so low-intensity magnetic separators are used to upgrade magnetite ores. On the other hand, because oxidized iron

    Magnetic induction is one of the most important factors controlling the recovery of target minerals during magnetic separation. As explained by Equation (4), the magnetic force (F m ) is proportional to the magnetic induction, which means that the recovery of magnetic minerals is promoted at higher magnetic induction
