Process simulations in mineralogybased geometallurgy of iron ores

Process simulations in mineralogybased geometallurgy of iron ores

The model parameters were calibrated for current runofmine ore and then in the simulation applied directly to the other ore. For the second ore, the simulation results vary between the different levels. This is because, at the bulk level, the model assumes minerals do not change their behaviour if ore texture or grinding fineness are changed.

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

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.
