Energy Consumption in Mining Comminution

2.1 Energy Consumption in Open Pit/ Underground Mines There is a dearth of information about energy consumption specific to individual mines. One study [6], which is a collaboration that compares seven mine mill/concentrator operations: four gold and three iron ore mines. The average energy needed for seven mines is summarized in figure 2, where

Copper Mining and Processing: Processing of Copper

Although the processing costs are higher, ultimately more copper can be extracted. Since each mine site is unique in its mineral composition, concentration, and quantities, the most economical and profitable processing of ore must be determined by the mine planners.

Mining

Usually, you will spend much less efforts if start mining from some lowland nearby. As you proceed with your tunnel, you have to correct the mining direction by prospecting the walls, floor and ceiling of the mine: search for the minimum radius where you prospect the ore in the direction of the mine.

Surface mining

It is most commonly used to mine coal and lignite (brown coal). Strip mining is only practical when the ore body to be excavated is relatively near the surface. This type of mining uses some of the largest machines on earth, including bucket-wheel excavators which can move as much as 12,000 cubic metres of earth per hour.

Aluminium life cycle

Aluminium has a life cycle that few other metals can match. It is corrosion resistant and can be recycled over and over again, requiring just a fraction of the energy used to produce the primary metal. This makes aluminium an excellent building material - reshaped and repurposed to meet the needs and challenges of different times and products.
