Energy efficient comminution circuits Mining processes require heavy capital investments and generates high operational costs which are mainly due to high energy consumptions. Of all the mining processes, grinding circuits are the most energy intensive component consuming up to 10 times more than crushing and 100 times more than blasting.The iron oxide mineral magnetite as Fe 3 O 4 has a mass percent of 72.36% Fe and 27.64% O and typically occurs as a natural ore containing 15–40% Fe. Historically hematite direct shipping ore (DSO) has been the preferred source of iron ore globally, with significant resources located on several continents, including Australia in the Hamersley Range, Western Australia.
