1.

IRON

  • Hematite
  • Cumbria, England; Elba, Italy

2.

GATHERING IRON

  • Raw ore is mined right from the ground combined with unwanted gangue
  • The ore is seperated from the gangue by washing away the lighter soil from
  • the crushed iorn ore
  • Iron ore is then sent to a bloomery to undergo the smelting process
3.

IRON ORE PROCESSING

  • Iron ores consist of oxygen and iron atoms bonded together into molecules
  • Iron ore undergoes a process to remove the oxygen to make metallic iron
  • Carbon is used because the strength of a carbon-oxygen bond is greater
  • than that of the iron-oxygen bond, at high temperatures
  • Iron ore must be powdered and mixed with coke, to be burnt in what is called smelting
4.

ENVIORNMENTAL IMPACTS

  • Air and noise pollution
  • Water contamination from smelting
  • Displacement of wildfire
  • Erosion and sediment
  • Soil degradation
5.
