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.

2019-11-1  Thus, the total specific energy for concentrating iron ore at the average ore grade (∼ 50% iron) from Thanatia (3.63% iron) was considered as the sum of the energy for the ore-handling process and the energy for concentration. In our model, the minerals for concentration are obtained from Earth’s crust; surface mining is assumed.

RENEWABLE ENERGY IN THE AUSTRALIAN MINING

Mining energy intensity – the energy required per tonne of product – is a function of definitions3, location, mining type, and processing type. Average energy intensity is estimated at 50.5kWh/tonne for coal, 10.7kWh/ tonne for minerals, and 54.5kWh/tonne for metals, with the majority consumed in diesel equipment and comminution operations4.

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
