Iron Ore Briquettes
Main advantages of iron ore briquettes. Lower CO2 emissions. Briquettes emit less carbon dioxide than traditional agglomeration processes (pelletizing and sintering). It can reduce CO2 emissions in the steelmaking chain by up to 10%. Lower gas emissions. Iron ore briquettes reduce emissions gases such as sulfur dioxide and nitrogen oxide.
