Mechanical activation (MA) of malachite was carried out by dry planetary grinding (DPG) and wet Isa grinding (WIG) methods. When the rotational speed was increased to 400 r/min in DPG, the specific surface area of malachite reached the maximum and the particle size reached the minimum of 0.7–100 µm. Agglomeration occurred between mineral particles when the rotational speed was increased to 580 r/min in DPG. However, no agglomeration was observed among particles with sizes 0.4–3 µm in WIG. X-ray diffraction analysis showed that, at a 580 r/min rotational speed in DPG, the amorphization degree of malachite was 53.12%, whereas that in WIG was 71.40%, indicating that MA led to amorphization and distortion of crystal structures. In addition, in the Fourier transform infrared (FT-IR) spectra of activated malachite, the bands associated with −OH, CO²⁻₃ and metal lattice vibrations of Cu-O and Cu-OH were weakened, and a new H-O-H bending mode and peaks of gaseous CO₂ appeared, indicating that MA decreased the band energy, enhanced dihydroxylation, and increased the chemical reactivity of the malachite. Furthermore, the leaching behavior of copper ore was greatly improved by MA.

孔雀石的机械活化（MA）通过干式行星研磨（DPG）和湿式Isa研磨（WIG）方法进行。当DPG的转速提高到400 r / min时，孔雀石的比表面积达到最大值，而粒径达到最小值0.7–100 µm。在DPG中，当转速提高到580 r / min时，矿物颗粒之间会发生团聚。但是，在WIG中，在大小为0.4–3 µm的颗粒中未观察到团聚。X射线衍射分析表明，在DPG中以580 r / min的转速旋转时，孔雀石的非晶化率为53.12％，而在WIG中为71.40％，表明MA导致晶体结构非晶化和变形。此外，在活化的孔雀石的傅立叶变换红外（FT-IR）光谱中，与-OH，CO相关的谱带^2- ₃的Cu-O和Cu-OH的和金属晶格振动而减弱，并且一个新的HOH弯曲模式和气态CO的峰₂出现，表明MA降低带能量，增强二羟基化，而且增加的化学反应性孔雀石。此外，MA大大改善了铜矿石的浸出行为。
