机械化学研究物质在机械力作用下所发生的化学和物理化学的变化。在超细磨过程中，矿物在晶体结构、活性等方面具有显著变化，处于高效失稳状态，反应活性增强。试验研究表明，利用超细磨过程中的机械力诱发化学反应，可以显著强化和改善矿物的浸出过程，在矿物加工领域具有广阔的应用前景。 Mechanochemistry studies the chemical and physicochemical changes of matter under mechanical forces. In the process of ultrafine grinding, minerals have significant changes in the crystal structure, activity and so on, in an efficient and unstable state, the reactivity is enhanced. Experimental studies have shown that the use of mechanical force induced by ultrafine grinding chemical reaction can significantly enhance and improve the leaching process of minerals in the field of mineral processing has broad application prospects.
