This is illustrated by Table 5, which compares reserve and resource lives for only operating mines with those for all deposits. As an example, when all deposits of iron ore are considered, the life of all resources, at 175 years, is far longer than the all resources life of 73 years calculated for operating iron ore mines.
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.
