its chemical formula is (Fe2O4)

it is one of the ores from which iron is extracted , And it is used in the manufacture of permanent magnets .

Magnetite has high acid and alkali resistance. Its hardness on the Mohs scale of hardness ranges according to its purity from 5.5 to 6.5 and density from 5.1 to 5.2 g / cm³.

Its uses :

it is used in Dense Media Separation (DMS). The magnetite powder is mixed with water to create a slurry or ‘dense media’, this allows objects of different densities to be separated using the sink/float method, magnetic drums help recover most of the magnetite from the separated material keeping consumption and costs low and also it used in  heat storage.

Typical applications include scrap separation, coal washing and mineral/ore concentration.
