Understanding the highgrade iron ore market

Understanding the highgrade iron ore market

levels in iron ores entering the DR furnace need to be particularly low to avoid prohibitive cost escalation at the EAF steelmaking stage. Only a few producers can supply iron ore pellets (and rarely lump) grades upward of 6667% Fe suitable for the DR route. Iron ores that can meet the grade requirements are known as 'DRgrade', and the premium they command over benchmark indices is .
