    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. The quality of the tools made from it was highly variable, depending on the region from which the iron ore was taken and the method used to extract the iron.

  • Blast furnace Wikipedia

    A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure. In a blast furnace fuel (coke), ores, and flux (limestone) are continuously
