The result indicates that the microwave treatment can cause physical structural changes on certain minerals, and the rock become more brittle. It can shorten and reduce the grinding time and energy. By microwave energy induced for 5, 15, 30, 60, 120, and 300 seconds prior to grinding, the work index was reduced by about 20 to 35%.
