— The model parameters were calibrated for current run-of-mine 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.

— What is iron ore? Iron ore is a mineral substance that generates metallic iron (Fe) when heated with a reductant. Iron ore generally comprises iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Hematite is widely considered one of the most important iron ores due to its high-grade concentrate of iron and its …
