There are than 14 types of magnetic separation of minerals.The magnetic fraction may be valuable or gangue depending upon its use in a particular flow sheet or process and so also the non magnetic fraction, e.g., separation of magnetite (magnetic) from quartz (non magnetic), separation of tin bearing mineral cassiterite (non magnetic) from magnetite (magnetic) impurity etc.

  • Magnetizing Roast And Magnetic Separation Of Iron In Rare

    Magnetic Separation is one of the physical concentration processes that utilizes the differences in magnetic properties of various minerals present in the ore body. The magnetic fraction may be valuable or gangue depending upon its end use in a particular process and so also the non magnetic fraction, e.g., separation of magnetite (magnetic).Apr 02, 2020 Diamagnetic minerals have negative magnetic susceptibility values, in the order of 5 x 10 8 m3 kg, and are repelled by a magnetic force. Diamagnetic minerals report to the non magnetic fraction of a dry magnetic separator. Knowing what magnetic properties your minerals contain allows you to effectively design processes and set up.

    Magnetic Separation Concentration of iron ore with low intensity magnetic separators has been used for decades in the recovery of magnetite. While gravity separation and froth flotation are two important processes for mineral beneficiation, other methods can be used to concentrate minerals and separate them from gangue and each other.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.
