Dri plant process

Apr 22, 2021

Jul 12, 2021 Direct reduced iron plant. This article is part of the Global Steel Plant Tracker, a project of Global Energy Monitor. Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, and/or fines) into iron with a sponge-like exterior, without melting

    Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BF-BOF and Scrap-EAF routes. In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction. DRI can then be transformed to steel in electric arc furnaces. DRI production is common in Middle East, South America, India and
