Abstract: A method for producing direct reduced iron or/and pig iron from an industrial waste materials stream such as EAF and blast furnace dust generally comprising the steps of separating the materials contained in the waste materials stream by magnetic separation or flotation, briquetting the iron-containing materials separated during the separation process with carbon, and providing the ...

Direct Reduced Iron (DRI) - .:: QITAPANDI-Home

Direct-reduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent.
