DRI production | International Iron Metallics Association

The Midrex® and Energiron gas-based processes use predominantly iron ore pellets as feedstock, but sometimes with inclusion of lump ore in the furnace charge. The Circored and Finmet / Finored gas-based processes utilize iron ore fines as feedstock.The SLRN coal-based rotary kiln process uses lump ore and, increasingly, pellets as feedstock.

Iron processing

Iron processing - Ores, Smelting, Refining: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and …
