How can steel decarbonisation technologies deal with the problem of low-grade iron ore?

Smelter technology addresses the issue of low-grade iron ore. All estimates point to widening supply crunch of DR-grade feedstock. Smelter filters out DRI impurities via slag which resembles that of a BF

Most projections indicate that while global steel production is likely to grow to 2.2 billion tonnes (bnt) by 2050, the share of the BF-BOF route, which accounts for over 70% of global steel production currently, will drop to around 35% by 2050. This is in sync with the gradual
