Customers producing steel in electric steel furnaces instead use our direct reduction pellets, commonly referred to as DR pellets. Our high pellet quality generates less slag, lower energy consumption, higher productivity and lower maintenance and wear in steelmaking. About 20% of our iron ore production is turned into magnetite fines (MAF).

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.
