While that’s partly a technological challenge, and one many of the world’s iron ore miners have taken on, there is a potentially bigger issue at hand. As iron ore expert and Magnetite Mines’ (ASX:MGT) Technical Director Mark Eames points out in a white paper released last week, high-grade iron ore is needed to transition to low-emissions steelmaking.

The main source of magnetite (Fe2+Fe3+2O4) is magnetite-bearing banded iron formations (BIF) and the key economic parameters for magnetite ore being economic are the crystallinity of the magnetite, the grade of the iron within the banded iron formation host rock and the contaminant elements, which exist within the magnetite concentrate.

· Iron ore is a mineral substance that generates metallic iron (Fe) when heated with a reductant. Iron ore generally comprises iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Hematite is widely considered one of the most important iron ores due to its high-grade concentrate of iron and its abundance.
