efficient sources of energy to gold mines

Energy efficiency • Energy intensity in copper and gold mining

Oct 01, 2017· 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.

Market Underestimates Energy Consumption By The Gold

Jan 25, 2018· 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.

TECH NEWS: Why mines should consider natural gas as energy

Aug 16, 2019· When looking at these figures, natural gas as an alternative energy source becomes much more attractive. A big advantage of piped natural gas is its affordability compared with LPG and electricity. It ranges between R150 and R320/GJ compared with LPG at R400 to R520/GJ (R20/kg to R26/kg) or electricity R350 to R622/GJ (R1.26 to R2.24/kWh).
