    Steel is usually about 99 percent iron, and the tight bond between iron and oxygen in iron ore explains much of the environmental cost of making steel. Now MIT professor Donald Sadoway has found a way to sidestep many of these drawbacks with a 1565° C process that uses electricity to separate iron and oxygen.

  • 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. Instead, the
