2015/2/24 0183 32The majority of steel production is supported by iron ore sourced from highgrade hematite deposits although a significant fraction comes from magnetite deposits. Compared to direct shipping hematite ores mined from the upper regolith magnetite deposits require significant beneficiation which typically involves grinding to a particle size where magnetite is liberated from its sili e matrix.

Magnetite Wikipedia

OverviewPropertiesDistribution of depositsBiological occurrencesAppli ionsGallery of magnetite mineral specimensSee alsoFurther readingMagnetite is a mineral and one of the main iron ores with the chemical formula Fe3O4. 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 of iron which is how ancient peoples first discovered the property of magnetism. Wikipedia 183 CCBYSA
