Average power consumption of gold mines
Average power consumption of gold mines. Dec 06, 2013 According to Dann Gwyn, Product Manager for Underground Mining at GE Mining GE, pany information, 10784190, Glen Lyn, VA, the deeper miners and equipment go into the earth, the less cost effective it is to use machinery running on diesel technology due to the large amount of ventilation infrastructure that is necessary to keep the working
average power consumption of gold mines
Mine ventilation can account for 30% to 40% of some deep underground mines total electricity consumption. Taking that into account, a variety of energy management options offer significant scope for improving mines electricity consumption profiles. Traditionally these mines have been ventilated and cooled on the basis of all-the-mine all-the-time.
Market Underestimates Energy Consumption By …
While the gold mining industry reports energy as only 15-20% of its total production costs, the total amount consumed by the industry is much higher. The market underestimates the amount of energy consumed by the gold mining industry because of the way it is listed in their financial statements. Thus, it takes a great deal more energy to produce gold than the market realizes.
Energy Consumption in Mining Comminution
operations: four gold and three iron ore mines. The average energy needed for seven mines is summarized in figure 2, where the energy requirement is broken down into six components: crushing, grinding, processing, tailings, process water, plant general (ancillary). Adding this energy to the average energy needed for an open pit mine, calculated as 11,766 kWh/kilotonne
