Iron mining in the United States produced million metric tons of iron ore in 2015, worth US billion. Iron ore was the thirdhighestvalue metal mined in the United States, after gold and copper. Iron ore was mined from nine active mines and three reclamation operations in Michigan, Minnesota, and of the iron ore was mined in northern Minnesota's Mesabi Range.

90% DIRECT REDUCED IRON (DRI) + HIGHGRADE SCRAP Ezz Steel converts iron ore into highpurity iron in four advanced direct reduction plants (DRP). Using the Midrex technology and the latest Danieli technology, these plants produce million tons of DRI per year, which is fed directly into electric arc furnaces in a continuous process.

hand, in DR processes where the iron is reduced in the solid state, the maximum temperature is below the melting point temperature and the reaction rates are slower. For direct reduction of iron ore, the mechanisms are complex because the oxide must go through a series of step wise changes before the conversion is complete.

The high grade iron product contains primarily metallic iron and can be marketed as a replacement of pig iron or DRI (Direct Reduced Iron) for steel mills. The medium grade iron product contains both iron oxide and metallic iron and can be utilized as a substitute for the iron ore in the blast furnace. The low grade iron product is rich in calcium, magnesium and iron oxides and silicates. It has a sufficient lime value .
