MIDREX

THE WORLD’S LEADING DRI PRODUCTION PROCESS

MIDREX is an innovative ironmaking process that has been specifically developed to produce direct-reduced iron from iron ores and natural gas/hydrogen.

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). MIDREX technology is highly customizable, which means it can be tailored to each customer’s specific needs, and this is reflected in a wide 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 process water degassing, hydrogen utilization, seal gas dry de-dusting system, slurry treatment, and the new and successful DRIpax process optimization system.
