Localized heating of the mineral particles causes the material’s microcracking and brittleness to result in more efficient grinding. The use of microwave heating will enhance this localized heating. High-energy mineral particles cause phase or chemical changes during prolonged heating (in seconds) or increased thermal energy, which creates more internal stresses and improves the next process. Studies have shown that microwave radiation is an effective method to improve the crushing of minerals because microwaves increase the transgranular and intergranular fractures of minerals.
