Underground mining generally results in relatively small waste rock disposal areas ranging from a few acres in size to tens of acres (0.1 km2). These areas are typically located near the openings of the underground workings. Open pit mining disturbs larger areas than underground mining, and thus has larger visual and physical impacts.

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.

The chemical reactions used to refine minerals also contribute to climate change. For example, one of the first steps in making steel is to heat a mixture of iron ore, limestone and coke, a coal product, to extremely high temperatures. This purifies iron by removing oxygen, but it also creates CO 2 and carbon monoxide as a byproduct. …
