2023年3月14日 For decades, the steel production industry has been one of the largest sources of CO2 emissions, accounting for 7% of global CO2 emissions, of which 70% is emitted in the iron-making process. Currently, the main low-carbon iron production route is hydrogen metallurgy, which uses renewable energy to generate electricity, electrolyze

Slag/Metal Separation from H2-Reduced High
Oolitic hematite ore, characterized by complex mineral phases, unique concentric oolitic texture and high phosphorus content, is considered to be one of the most refractory iron ore resources. It is widely distributed in France, Canada, Saudi Arabia and China.1) There are approximately 22 billion tons of high-phosphorus iron ores with an average of 1.0 wt%

Intensification of waste gangue removal from 6–1 mm fine
Density-based dry separation with a vibrated fluidized bed was performed to investigate the segregation and separation of 6–1 mm fine-sized iron ore through the removal intensification of waste gangue. The 6–3 mm and 3–1 mm iron ore samples were a typical hematite with total Fe-grades of 46.5% and 46.2%, respectively.
