High-grade iron ore supply to struggle to meet demand as ...

2021-6-9  Demand for high-grade ore is also expected to benefit from decarbonization due to its lower impurities and the higher productivity that it offers. Impurities such as alumina and silica in ore need to be removed using coke and limestone in iron making. Iron ore with lower impurities consumes less coke and limestone and therefore emits less carbon.
