Iron ore grindability improvement by microwave pre-treatment
Ore grinding is a cost- and energy-intensive process in which the wear of balls is a significant practical problem leading to a substantial increase in the production cost. With the present trend towards utilization of low grade ores requiring finer grind for liberation, the amount of media wear per tonne of concentrate recovered is steadily on
