The Ore Grade and Depth Influence on Copper Energy

The study evaluated implications of different ore grades and mine-depth on the energy inputs to extract and process copper. Based on a 191 value dataset from 28 copper mining operations, seven model equations explaining operational energy costs were statistically evaluated. Energy costs for copper mines with leaching operations were not found to be significantly affected by ore grades nor mine

Modelling future copper ore grade decline based on a

2014-2-1  As copper ore grades decline, the environmental impacts of primary Cu production will generally increase, along with other associated costs (Norgate and Haque, 2010). LCA studies show that the level of this increase is dependent on the type of processing utilised to produce Cu ( Alvarado et al., 1999,Norgate and Haque, 2010,Norgate and
