Avoided energy cost of producing minerals: The case of iron ore
2019111 Thus, the total specific energy for concentrating iron ore at the average ore grade (∼ 50% iron) from Thanatia (3.63% iron) was considered as the sum of the energy for the ore-handling process and the energy for concentration. In our model, the minerals for concentration are obtained from Earth’s crust; surface mining is assumed.
