Developing Low-silica DR-grade Pellets. Direct Reduced Iron (DRI) is a high-quality metallic product (~90% pure iron) produced by the direct reduction of iron oxide at a temperature below the fusion point of iron. It is primarily used in electric arc furnaces (EAF) but can also be used by blast furnaces and other iron and steelmaking applications.
