Low-grade hematite ores, on the other hand, need to be upgraded to achieve the required iron content which involves more complicated ore beneficiation processes. The level of comminution required for the low-grade hematite ore is similar to high-grade ores to deliver products of the same size specifications, lump and fines.

That could fall to $489/ton by 2050 and compete with today's production technologies, Attwood said. However, if higher-grade iron ores are in short supply, yields could be reduced, increasing that $489/ton price tag by 20%. According to Wood Mackenzie, in 2020 the global average cash cost for finished steel was about $415/ton.
