Because of the intensive activity of North China Craton during geological history, the long-term supergene weathering–leaching condition for generating high-grade hematite ore is deficient. Therefore, BIF-related ores in China are mainly magnetite-dominated low-grade iron in the sedimentary–metamorphic iron deposits.
Hydrogen Reducibility of low-grade magnetite iron ore pellets investigated. ... Though the current cost of H 2 is high, it is estimated that in countries like Brazil, China, India, Sweden; the cost of green H 2 will become less than gray H 2 by 2030 (Blog, 2022, Blog, 2023). The reduced costs could make hydrogen a potent alternative to ...

The studied BIF ore samples have a narrow range of TFe between 30.90 wt.% and 43.20 wt.%, indicating a low-grade ore. The geochemical signatures of magnetite such as low contents of base metals (e.g., Cu, Co, V, and Zn) and low Co/Zn ratios < 0.85 indicate a hydrothermal origin.
In arid and severely cold regions such as west China, a plenty of iron ores are difficult to be economically utilized due to water scarcity [1, 2], so that the utilization for such iron ores has an urgent demand for high-efficient dry magnetic separation (DMS) technology [[3], [4], [5], [6]].A large portion of iron ores were currently processed in wet magnetic separation …
