  • How much iron ore is needed for 1 tonne of steel rebar

    Typically, it takes 1.6 tonnes of iron ore and around 450kg of coke to produce a tonne of pig iron, the raw iron that comes out of a blast furnace. Around 0.6 tonnes (600 kg) of coke produces 1 tonne (1000 kg) of steel , which means that around 770 kg of coal are used to produce 1 tonne of steel through this production route.
