Understanding the high-grade iron ore market

Iron ore concentrates are ores that have been mechanically processed to increase their iron content and decrease impurity levels. Iron is not a rare commodity – it's the fourth most abundant element in the earth's crust, making up around 5% – but zones that can produce high-quality DSO are finite. Thankfully, there are ample resources of

Currently, all available technologies require agglomeration, like pelletizing to produce DRI or HBI. An additional challenge steel producers face, is the reduced quality of iron ore, resulting in the need to beneficiate the iron ores. In order to progress to a CO2-free steel production, a process using mainly H2 is most desirable.
