Environmental impact of iron ore mining - Wikipedia

After the iron ore is out of the ground, it may be shipped to the iron and steel manufacturing plant. If the ore contains less than 60 percent iron, it is usually beneficiated to an iron-ore concentrate typically containing greater than 60 percent iron. This is done by separating the iron minerals from the valueless minerals, usually by magnetic, gravity, or froth floatation.

Magnetic Properties of Solids - HyperPhysics Concepts

A positive relative permeability greater than 1 implies that the material magnetizes in response to the applied magnetic field. The quantity χ m. is called magnetic susceptibility, and it is just the permeability minus 1. The magnetic susceptibility is then zero if the material does not respond with any magnetization. So both quantities give the same information, and both are dimensionless ...

Permeability (electromagnetism) - Wikipedia

Paramagnetic materials are attracted to magnetic fields, hence have a relative magnetic permeability greater than one (or, equivalently, a positive magnetic susceptibility). The magnetic moment induced by the applied field is linear in the field strength and rather weak. It typically requires a sensitive analytical balance to detect the effect. Unlike ferromagnets, paramagnets do not retain ...
