Wyllie, "In-Pit Crushing Still Gaining Ground in Open Pit Mines,"Engineering and Mining Journal, June 1987, pp. 76-80.

Figure 3 looks at the top 10 energy intensive processes in coal, minerals and metals. It is no surprise that grinding is the largest energy intensive process. Figure 4 is interesting in that it looks at the potential for energy savings for the coal, metals and mineral industries within the USA.

between 0.80.9 kg/kWh, seven plants use between 0.9- 1.0 kg/kWh, and at three plants - coal usage exceeds 1.0 kg/kWh. Hence the efficiency of the plants and the coal usage per unit of electricity generation also differ at each plant. There is a need to modernize India's thermal power plants and reduce the coal usage per unit of electricity ...

energy in aluminium produced using electricity that is coal-based, natural gas-based and nuclear energy-based is approximately 22.4, 13.3 and 9.9 kg CO 2 -e/kg Al, respectively. The energy required to recycle metals is a relatively small fraction of the energy required to

According to world coal association, over 41% of global electricity production is dependent upon coal where coal is dominant fuel/source of electricity generation particularly in south africa, poland, china, india, australia and other countries including the usa, as shown in following figure:

The HPGR-ball mill circuit when grinding to 75 um compared to 160 um used an extra 4.6 kWh/mt, but for the SABC circuit it only used an extra 1.8 kWh/mt. The reported SABC circuit power for the 160 μm grind size was based on actual site data.
