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.
