| Malachite, a copper carbonate hydroxide mineral with the formula Cu2CO3(OH)2 was mechanically activated for different durations in a planetary mill and analyzed by means of scanning electron microscopy, X-ray diffraction, Fourier transform: infrared spectroscopy and particle size analysis to investigate the structural alterations in malachite structure. The results showed that decrease in intensity of the X-ray diffraction peaks and some alterations in carbonate and hydroxyl units of malachite occurred with increase in mechanical activation duration. |
