Magnetic methods are more popular in mineral exploration than gravity, not least because magnetic data can be quickly recorded from the air and in conjunction with other geophysical surveys. Land gravity surveys, by contrast, may require greater field efforts (Figs. 1, 5 and 6), more time, and more commitment of scarce capital.

Magnetic separation is most commonly used in the mining industry to separate "tramp ore," or unwanted waste metals, from the rest of the bulk material. Tramp ore typically consists of the man-made byproducts created by the mining process itself, such as wires from explosive charges, nuts and bolts, nails, broken pieces from hand tools such ...

In the actual magnetic separation machine, the magnetic field strength ranges from hundreds of Gauss to 20,000 Gauss, some even exceed 20,000 Gauss, but it is rarely used in general beneficiation production. Excessive magnetic field strength will lead to weak magnetic minerals to agglomerate that is not conducive to beneficiation.
