Iron Ore | Earth Sciences Museum | University of Waterloo

Smelting involves heating up the ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. This process releases oxygen from the ore, one of the most common impurities in the metal. The facility used to smelt the iron is referred to as a bloomer. There, a blacksmith burns charcoal with iron ore and a good supply of oxygen. The carbon in the charcoal combines ...
