Mining crushing grinding costs
The purpose of this data-file is to tabulate typical cost estimates for crushing-grinding processes, which consume 1-2% of all the energy in the world and 20-50% of the energy in some mining processes. Our numbers are shown per ton of ore, so clearly lower ore grades translate into higher costs per unit of extracted material ().Energy economics.
