The magnetic oxide of iron, Fe. O4 , contains a theoretically larger amount of iron ( 72.4 per cent.) than any other commercial ore. It is probable that it has originated in many cases by the prolonged exposure of the hydrated oxide, 2Fe2O 3 + 3H20 to heat and pressure which converts it first into hematite, Fe20 3, and then into magnetite. It would thus appear as if nature had already done part of the work of removing all the oxygen and that magnetite should be relatively easy to reduce.
