Magnetic Separation - Mine Engineer.Com

Magnetic separation is generally a low cost method of recovery, unless high intensity separators are required. The electro-magnetic high intensity separators that produce 20,000 gauss, tend to be expensive. However, the rare earth magnetic separators are relatively inexpensive and can produce magnetic fields around 6,000 gauss.

Magnetic Separation - Mining Fundamentals

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.
