driDirect Reduced Iron (DRI) is a metallic material produced from direct reduction-oxidation of iron ore using a reducing gas (a chemical transformation process that removes Oxygen and Carbon without reaching the melting point of iron). It usually contains between 90 and 94% total iron and low amounts of residuals.

It is used in the production of steel, primarily in electric arc furnace mini-mills to increase their efficiency, among other advantages, by diluting the impurities contained in the scrap metal used in this process.
