Process of Steel-making from Iron Ore
Its production process is basically similar, melting pig iron into hot metal and then adding some substances in the hot metal, such as oxygen, and iron ore, which makes it react with the carbon in the hot metal so as to reduce the carbon content in the hot metal. Then pour the purified hot metal into the mold and make it into steel after cooling.

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.
