Market Underestimates Energy Consumption By The

2018-1-25  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

Gold & Silver Energy

2013-11-8  In 2000, gold was produced at 641 load mines; about a dozen large placer mines; and numerous small placer mines. In addition a small amount of domestic gold was produced as a byproduct of processing base metals.2 Silver was produced in the United States from precious-metal ores at about 30 lode mines and from base-metal ores at about 24 lode mines.

Energy efficiency • Energy intensity in copper and gold

Mines are faced with numerous challenges, such as falling raw material prices, declining metal grades in the ores and higher energy prices. Especially because ore processing is particularly energy-intensive, the industry is again focusing on the saving of energy. This report shows what are the key energy saving considerations in the copper and gold mining sectors.
