Both are accomplished by melting the iron ore at a very high temperature (1,700 degrees Celsius or over 3,000 degrees Fahrenheit) in the presence of oxygen (from the air) and a type of coal called coke. At those temperatures, the iron ore releases its oxygen, which is carried away by the carbon from the coke in the form of carbon dioxide. Fe 2 O 3 (s) + 3 CO(g) → 2 Fe(s) + 3 CO 2 (g)
Copper ore, in concentrations ranging from 0.29 percent to ten times that amount, is mined from open pit or underground mines.
