Eco-efficient and cost-effective process design for magnetite iron ore .

It is very well known that energy production also implies emission of CO2, as shown in Figure 1 (.ceecthefuture). The information indicates that almost 50% of the total CO2 emissions are generated by the comminution processes (crushing and grinding operations). For this reason, it is crucial to innovate through.
