CO2‑free flux for sustainable iron ore pelletizing

The iron and steel manufacturing sector directly accounts for 7 to 9 percent of global carbon dioxide (CO2) emissions. Raw material preparation — such as iron ore sintering, pelletizing and coke making — is the major CO2 emitter. As climate change becomes a bigger concern, steel manufacturers need to lower CO2 emissions without hindering efficiency or increasing costs. In recent years, the percent...
