CO 2 -Free Flux for Sustainable Iron Ore Pelletizing
The iron and steel manufacturing sector directly accounts for 7–9% of global CO 2 emissions. Raw material preparation, such as iron ore sintering, pelletizing, and cock making, is the major CO 2 emitter. As climate change becomes a bigger concern, steel manufacturers need to lower CO 2 emissions without hindering efficiency or increasing …
