Avoided energy cost of producing minerals: The case of iron ore

Thus, the total specific energy for concentrating iron ore at the average ore grade (∼ 50% iron) from Thanatia (% iron) was considered as the sum of the energy for the orehandling process and the energy for concentration. In our model, the minerals for concentration are obtained from Earth's crust; surface mining is assumed.
