Mar 07, 2017 Iron Smelting is the process of making iron ore into iron. The smelters heat up the iron ore to melting point using charcoal as fuel. They then cast the heated iron ore into ingots called pigs. The ingots were either reheated and cast into moulds or they were heated and hammered into wrought iron which is more malleable.

Iron, when extracted from iron ore such as haematite containing iron (III) oxide, Fe2O3, in a blast furnace is called iron extraction blast furnace metallurgy. In this reduction reaction, oxygen is removed from the iron (III) oxide to leave behind iron. Generally, the extraction of metals and their isolation are based on three major procedures.
