Iron Ore | HowStuffWorks

Charcoal is essentially pure carbon. The carbon combines with oxygen to create carbon dioxide and carbon monoxide (releasing lots of heat in the process). Carbon and carbon monoxide combine with the oxygen in the iron ore and carry it away, leaving iron metal. In a bloomery, the fire doesn't get hot enough to melt the iron completely.
