mining

The cut-and-fill mining method is used to mine ore deposits of this type because it provides adaptability to all of these variables. Its name is derived from the way the ore is mined. The ore is removed, or cut, from a small segment of the ore body—about 20 to 4,000 cubic feet (0.6 to 113 cubic meters)—and then waste rock is placed back ...

IDENTIFYING OPPORTUNITIES TO REDUCE THE …

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
