"Increased focus on magnetite mining is one option. Magnetite iron ore is often more suitable and preferable for further processing and producing iron ore concentrate and pellets of DR-grade quality," says Basirat. "There may also be the possibility of beneficiation of some existing iron ore production towards DR-grade."

Some impurities, such as phosphorus, are costly to remove and otherwise affect steel quality. So it makes sense that steelmakers want higher grade ore with less impurities. "There is a big difference between a 65 per cent ore and a 55 per cent ore – roughly three times the impurity levels," Eames explained.
