Opis:: Smithsonite, ZnCO₃, from Zamantı-Kayseri, Turkey, was subjected to high-energy milling. X-ray diffraction analysis was performed to study amorphisation in the structure and the alterations of bands in the structure were investigated by Fourier transform infrared spectroscopy. Characterization of milled smithsonite by X-ray diffraction analysis has shown that disappearance, decrease and/or shifting of the patterns occurred with mechanical activation, which means that amorphisation was taking place. Amorphisation was also demonstrated by Fourier transform infrared spectroscopy analysis, where shifting of band centers was observed.

Opis:: Malachite, a copper carbonate hydroxide mineral with the formula $Cu_2CO_3(OH)_2$ 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.

Opis:: The lateritic nickel ore was activated mechanically in a planetary ball mill and mineralogical analyses of nickeliferous laterite have been studied by particle size analysis, scanning electron microscopy, X-ray diffraction, and the Fourier transform infrared spectroscopy. The results show that the activation procedure led to amorphisation, phase transformation and structural disordering in the laterite structure.
