    and charcoal could be made as long as the iron ore lasted. Reduction of iron ore to pig iron became big business in the late 1800's and early-1900’s. Local blast furnaces furnished an outlet for much of the early iron ore production. Up to 1903, all Michigan pig iron was smelted with charcoal. At that time coke from coal was introduced

    Direct reduced iron - Wikipedia

    Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) into iron by a reducing gas or elemental carbon produced from natural gas or coal.Many ores are suitable for direct reduction. Direct reduction refers to solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting
