Atmospheric hydrochloric and nitric acid leaching of a limonite ore from the Wolo mine area, Southeast Sulawesi, Indonesia
Deskripsi The atmospheric acid leaching studies of a limonite ore sample from the Wolo mine area, Southeast Sulawesi, Indonesia, have been performed using hydrochloric acid (HCl) and nitric acid (HNO 3 ).The objectives of these studies were to compare the leaching degree of metals (Ni, Co, Fe, and Al)and to analyze the dissolution behavior of minerals under different acid concentrations. Mineralogicalcharacterization of the ore sample was conducted using optical microscopy, scanning electron microscopy(SEM), and X-ray diffraction, whereas chemical composition was determined by X-ray fluorescence (XRF)spectrometry and atomic absorption spectroscopy (AAS), respectively.
