The Ore Grade and Depth Influence on Copper Energy Inputs
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 …

Improved grade control in open pit mines | Semantic Scholar
Grade control in hard-rock open pit mining is the process of determining the destination for the mined material. Numerical studies are undertaken to show how grade control can be improved, that is, less ore sent to the waste dump and less waste sent to the mill. The improvements in four aspects of grade control are proposed: (1) the grade predictions should …
