Before iron ore can be used oxygen must be removed from it. Known as reducing this can be done either in the blast furnace where hot air is injected into a continuous feed of coke sinter and lime or by the direct reduced iron (DRI) process. The result from both is liquid iron which is then transported to the basic oxygen furnace.
