Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion.

Roasting is a metallurgical process that converts sulfide ores to oxides before smelting. It varies from calcination in that the chemical change in calcining limestone or other carbonate ores is accomplished solely through the application of heat, whereas roasting entails an interaction between gas and the solid ore. The reaction is exothermic.
