The Ore Grade and Depth Influence on Copper Energy

2016-11-22  where \(E\) is the processing (by extraction and milling/flotation or leaching) energy usage in MJ per kg of copper concentrate at 30%+ purity or copper in pregnant leach solution. The fixed energy cost parameter \(\beta\) is divided by an ore grade variable \(G\) in percentage of copper per mass of ore extracted, so as to capture changes in energy costs.

Benchmarking comminution energy consumption for

2014-10-15  For gold producing mines the average energy was 353 kW h/oz and for copper it was 1134 kW h/t. The Battelle Columbus Laboratories (1975) reported the comminution energy intensity of gold and copper to be 42.9 kW h/oz and 3410 kW h/t respectively. It is interesting to see that the processing of gold was found to be significantly more energy intensive, in our work, but copper required less energy.

Energy efficiency • Energy intensity in copper and

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.
