Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.

Pellet plant is facilitated with additives grinding unit as the process of pelletization requires binder and additives. Bentonite is used as a binder for proper balling of the filter ...

What are particles? Iron ore pellets, like concentrates, are raw materials for the manufacture of iron, which is pulverized and ground into pellets ranging from 0 to 100 microns for supply to industry as pellet feed. Green pellets and hardened green pellets are used in the direct reduction process to produce iron. Raw materials for […]

The shaft furnace is where iron ore is converted to metallic. Iron oxide, in pellet or lump form, is introduced through a proportioning hopper at the top of the shaft furnace. As the iron ore descends through the furnace by gravity flow, it is heated, and the oxygen is removed from the iron ore (reduction) by counterflowing gases that have a ...

Best-in-Class Steel Producer. Cleveland-Cliffs is the largest flat-rolled steel producer in North America. Our competitive advantage as an integrated steel company is based on our ability to operate the entire production flow from the extraction of iron ore, to steelmaking, rolling, coating, finishing, stamping and tooling steel products.
