基于同步辐射技术的黄铜矿浸出机理研究,李育彪,武汉理工大学,Synchrotron is widely applicable in minerals processing;Chalcopyrite oxidation took place heterogeneously at sub-micron scale;Surface roughness increased on increased leaching time due to the growth/overlap of oxidised sulfur species;Both the addition of Fe2+ and pyrite in contact with chalcopyrite enhance chalcopyrite oxidative dissolution significantly, with the latter being more effective in improving oxidation;
