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.

It is possible that metals will not physically run out but will …
The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …

How steel is made. First, the raw materials, either iron ore or scrap iron (depending on the process), are converted into molten steel. The ore-based process uses a blast furnace or smelter and the scrap-based process uses an electric arc furnace. Next, the molten steel is poured and solidified in a continuous caster.
