Magnetite - Wikipedia

Magnetite is a rock 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. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces ...

ACARP Abstract

The loss of magnetite has also decreased markedly. The overall value was 0.43 tph compared to 3.75 and 1.60 for the base case with improved magnetic separation capability and the use of more sieve bend width respectively. The magnetite losses to the product, reject and overflow from the magnetic separators were 0.13, 0.26 0.04 tph respectively.
