  • How iron is madematerial manufacture making history

    Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 92-94 iron and 3-5 carbon with smaller amounts of other elements. Pig iron has only limited uses and most of this iron goes on to a steel mill where it is converted into
