Iron ore concentrates are used as a metallurgic raw material in iron smelting with grade between 70 and 72.3% Fe. Iron ore concentrates are characterised by low sulphur and phosphorus content. Iron ore concentrate recovery is based on magnetic beneficiating methods.
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
