Magnetite - Wikipedia

Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 4. It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth.

of a magnetic separator to lift a particular mineral is dependent not only on the value of the field intensity, but also on the field gradient, which is the rate at which the field intensity increases towards the magnet surface [6]. Production of a high field gradient as well as high intensity is therefore an important aspect of separator design.
