Energy and Environmental Profile of the U.S. Mining Industry 4
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.
Energy Consumption in Mining Comminution
energy consumption on an average mine site. Globally it is estimated that all pumps consume 15% of available electricity. In addition, HVAC energy requirements can be at least 25% of underground mine energy needs [10]. Mining energy consumption contributes to mining operational costs and occurs at all stages of the ore recovery
