NEW DELHI--May 22, 2023--Researched by Industrial Info Resources (Sugar Land, Texas)--Making steel--the process of converting iron ore into liquefied iron and liquefied iron into steel--uses a lot of energy and is a leading cause of greenhouse gas (GHG) emissions. Most of these emissions are created during the industrial process of transforming iron ore--the raw material--into a liquefied state. One solution for this problem is direct reduction of iron ore.
