Types of Iron Ore: Hematite vs. Magnetite INN

The mineral magnetite actually has higher iron content than the mineral hematite. However, while hematite ore generally contains large concentrations of hematite, magnetite ore generally holds low .

Iron ore Wikipedia

Magnetite is magnetic, and hence easily separated from the gangue minerals and capable of producing a highgrade concentrate with very low levels of impurities. The grain size of the magnetite and its degree of commingling with the silica groundmass determine the grind size to which the rock must be comminuted to enable efficient magnetic .

Busting the myth that magnetite cant be profitable Stockhead

Haematite is higher grade in the ground, while magnetite deposits are large and quite low grade but produce very highgrade products. But it is actually not that hard to upgrade magnetite to a highergrade material using magnetic separation basically you just grind the material and place it under a big magnet that captures the magnetite .

Recovery of magnetite from low grade banded magnetite .

There has been a steady increase of iron ore demand in the last few decades. This growing demand could be countered by use of low grade iron ore after beneficiation. Banded iron formations BIF are one of the resources of such low grade iron ores. Banded magnetite quartzite BMQ is one such BIF and a source of iron phase mineral in the form of magnetite. In the present study a low grade BMQ .
