North Africa: Focus on Direct Reduction Ironmaking - …

Direct reduction of iron – extracting metallic iron from iron ores without melting the material – is one of the first industrial processes developed by humans. Early ironmakers were unable to achieve the high temperatures required to melt iron ores, so they heated them together with charcoal to produce a pasty, metallic substance which they could hammer into tools and other implements.

Direct Reduced Iron (DRI) - Cargo Handbook - the …

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. This process of directly reducing the iron
