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.
Sulfide Mining Fact Sheet
deposits are very deep, and in open-pit mines when the deposits are relatively shallow.i Once the metals have been separated from other rock, the mining operator must find ways to dispose of the substantial waste rock. Sulfide mining is different from traditional iron ore mines and taconite mining (sometimes referred to as ferrous mining).
