pig iron from iron ore process

Mar 20, 2017 At any place where there is a market demand for steel, and pig iron can be made in the electric furnace at a profit, the steel ultimately produced would be cheaper, if made by the electric reduction of iron ore to pig steel, followed by refining in another furnace if necessary, than if the product of the electric-reduction furnace was pig iron to be subsequently converted to steel in another furnace

    What Is Involved in Pig Iron Production? (with pictures)

    Iron ore is combined with charcoal in a blast furnace to create pig iron. The process of pig iron production involves the combination of iron ore, charcoal, and an intermediary material known as a flux inside a blast furnace. As the materials combine with intense heat, much of the iron ore melts, creating a
