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 ...
