摘要: In this work, FeCl3 solution was used as a lixiviant to leach Ni, Co, Mg, and Mn from saprolitic laterite ore. Investigation into the leaching of these metals precipitation Fe in lixiviant, found optimal conditions be temperature 150 degrees C, concentration 178.9 g/L, liquid solid ratio (L/S) 1.0, time 90 min. The kinetics process also discussed. Saprolitic ore with without goethite seeds leached using under identical conditions. X-ray diffraction (XRD) analysis, infrared spectrometry (IR), mineral liberation analysis (MLA) were characterize residues. mechanism analyzed based on results. (C) 2015 Elsevier Ltd.
