Jun 30, 2016· Magnetite is an iron oxide mineral that is generally black in colour and highly magnetic; the latter property aiding in the beneficiation of magnetite ores. Magnetite contains % iron, which is higher than hematite, but the presence of impurities usually results in magnetite ores having lower ore grade (generally 2030% Fe) than hematite ores, making it more costly to produce concentrate for .
