November 17, 2006 A new manufacturing process developed appears set to make the production of iron much more environmentally friendly. The outstanding feature of the “Corex process” is that it uses conventional coal instead of coking coal, the customary ingredient. The world’s largest Corex-based plant is currently being built in China and is scheduled to begin operation in late 2007. It does not require a coking plant, reducing the discharge of dust and nitrogen oxides by more than 90 percent and sulphur dioxide emissions by 97 percent.
