Effects of Mechanical Activation on the Structure of Nickeliferous Laterite

Abstract

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 diraction, 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.
