High-Quality Magnetite
Historically, hematite was the preferred iron ore due to its direct usability in blast furnaces (BF) for steel production, without beneficiation (value improvement) costs. But with declining hematite ore quality and a shift towards low-carbon technologies such as DRI, the demand for high-quality magnetite ore is at historically high levels.
