Steel Production Environmental Impact

The most common process is the use of a blast furnace to produce pig iron which is about 9294 iron and 35 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 various steel alloys by further reducing the carbon content and adding other elements such as manganese and nickel to give the steel specific properties
