The main ingredient in the production of steel is iron ore mined from Earth. Over 2,000 million tons of iron ore is mined mined a year - about 95 percent is used by the steel industry. Iron ore is the world's third most produced commodity by volume - after crude oil and coal - and the second most traded commodity - only beaten by crude oil.

4.1.1 Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or open-pit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions. Small, low-capacity mines have rapidly disappeared.
