Magnetite is a mineral whose primary component is an iron oxide that contains equal amounts of iron (II) and iron (III). Its empirical formula is Fe 3 O 4, and it is often expressed as iron (II,III) oxide. In the past, it has been called ferrous–ferric oxide and triiron tetraoxide. Magnetite is found in igneous, metamorphic, and sedimentary ...
Magnetite is the catalyst for the production of ammonia. Approximately 2–3% of the world's energy budget is allocated to this chemical process. It increases the reactivity between nitrogen and hydrogen to make ammonia. It is also used to catalyse the breakdown of hydrogen peroxide, used to remove many industrial contaminants.
