DRI production | International Iron Metallics Association
DRI production. 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.

Applications of Iron Ore Pellets
Usually, Iron Ore is manufactured and converted into Pellets. These are oval lumps of iron ore that are hardened using fuel. This process of converting iron ore into pellets is known as Pelletization. Iron Ore Pellets are then used in the production of steel. Pellets are usually preferred instead of raw Iron Ore because it allows for maximum ...
