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.

Open-pit mining. Open-pit mining is the activity of removing the earth to access the mineral deposits and continuing to do it vertically in an open-pit. This method is best suited for mineral deposits that are close to the surface of the earth but are not accumulated in a horizontal manner. Open-pit mining often impacts a narrower surface area.

In addition to steel prices, the health of China's economy is strongly linked to iron ore prices. As China's economy has slowed in recent years, so has demand for iron ore and prices have consequently fallen. Iron ore prices averaged over USD 130 per metric ton in 2013. Last year they averaged just over USD 58 per metric ton.
