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.

Mining in Western Australia has been dominated by a select group of commodities, initially gold in central WA from the 1890s, followed by the rise of iron ore, nickel, and bauxite–alumina in the 1950s–1960s. Other commodities have also made important contributions, such as mineral sands, diamonds, coal and base metals.
