Jan 28, 2012 · Magnetite and hematite are important oxides of iron. Though there are several differences between them, the key difference between magnetite and hematite is that the iron in magnetite is in +2 and +3 oxidation states whereas, in hematite, it is only in +3 oxidation state. Magnetite is black in colour, but hematite has

The majority of steel production is supported by iron ore sourced from high grade hematite deposits, although a significant fraction comes from the magnetite deposits. Compared to direct ship 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 silicate matrix.

Braemar ore deposits are unusually soft and only slightly abrasive when compared to typical taconite or BIF deposits. The Braemar deposits therefore offer competitive grinding cost advantages. Braemar magnetite grains occur in a matrix of soft siltstone and shale and break readily along grain boundaries.
