Midrex® – the world’s leading DRI production process
Midrex is an innovative ironmaking process, developed for the production of direct-reduced iron (DRI) from iron ores and primarily natural gas.
Midrex is a gas-based shaft furnace process that converts iron oxides – in the form of pellets or lump ore – into direct reduced iron (DRI). The Midrex technology is highly adaptive to our customers’ needs, which is reflected in a broad variety of configurations. The performance of Midrex plants typically exceeds nominal capacity ratings. This trend will continue with the implementation of new technologies such as oxide coating, oxygen injection, OXY+, centrifugal process gas compressors and our process optimization system. As a licensee of Midrex technology, Primetals Technologies has been successfully building Midrex direct reduction plants and is able to supply all sizes of packages right up to turnkey solutions. About one third of all Midrex plants worldwide have been built with significant involvement (e.g., consortium leadership) of Primetals Technologies.
