iron ore energy consumption

Iron and Steel – Analysis - IEA

Scrap-based production (also referred to as secondary or recycled production) can be valuable in reducing energy demand and CO 2 emissions, as it is considerably less energy-intensive than primary production from iron ore. Scrap is used as the main ferrous feed in electric arc furnaces (EAFs), as well as in induction furnaces to a lesser extent.
