Pilot-scale optimization of atmospheric acid leaching for enhanced nickel and cobalt recovery from laterite ore

Nickel and cobalt are critical metals predominantly extracted from laterites. However, deposits with high iron content (>15%) and SiO2/CaO + MgO ratios (∼1.8) limit the applicability of conventional pyrometallurgical routes. In this scenario, hydrometallurgical processes, particu...
