DRI: This iron production process directly reduces iron ore in solidstate with the reaction temperature below the melting point of iron. Reducing gases are produced from natural gas (gasbased DRI) or coal (coalbased DRI) called syngas, a mixture of H 2 and CO. Although DRI production is more energy efficient than pig iron production from BF ...
