Hydrogen reduction of low-grade banded iron ore
India possesses abundant low-grade banded iron ores and are generated during the conventional mining of hematite ores, and due to the lack of beneficiation technologies, they end up in stockpiles at the mine sites (Rayapudi et al., 2019, IBM, 2020). The complex association between quartzite and hematite values leads to the …Web

Hematite currently dominates iron ore mining - the bulk of direct shipping ores (DSO) are hematite such as Australia's Pilbara mid-grade iron ore. Magnetite ores tend to have a much lower Fe content but are often suitable for significant beneficiation -- in part because magnetite is magnetic which can make separation easier -- to DR-grade.Web
