Abstract:A nickel laterite ore sample from the Obi Island of North Maluku, Indonesia was thermally treated using corncob charcoal as a reductant to determine the effect of corncob charcoal addition on the chemical change and phase transformation. Mineralogical analysis of raw ore sample and calcines was performed using optical microscopy and X-ray diffraction methods, whereas chemical composition was determined employing X-ray fluorescence (XRF) spectrometry. The ore was then calcined at 1.000°C for 1 hour with the mas… Show more
