Energy Use in the Mining Industry TheWorldCounts

Iron ore Mining uses some of the heaviest machinery on the planet. The largest of these machines can weigh up to 13,000 tonnes (3,700 African elephants) and are able to remove 160 cubic meters of soil in one single go (more than the world's annual gold production).

benchmarked the energy consumption of open cut iron ore and gold mines. In investigating iron ore in an open cut mine, it was reported that there was potential to reduce the mining costs (based on energy savings) by 36% and milling costs by 47%. For gold mining this estimate was reduced to a staggering 53% for milling. Examples of Energy Events

Energy and Environmental Profile of the U.S. Mining

2013-11-8  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.
