Iron ore grindability improvement by microwave pre

2010-9-25 · However, based on energy saving alone, microwaving to improve the grindability of the iron ore was not cost effective. By improving the grindability, changes occur in the grinding circuit that may decrease comminution costs. If the iron ore is easier to grind, there would be less wear of the mill, mill liner, and milling medium.
