中文摘要:
      本文针对CIGS废料采用“硫酸化蒸硒-水浸-铜萃取-铟萃取-中和沉镓-碱化造液”工艺梯次回收硒、铜、铟、镓四种元素,并产出粗硒、阴极铜、精铟和金属镓产品。在优化后试验条件下,蒸硒过程硒挥发率为99.5%,萃取过程铜、铟的萃取率分别为98.4%和99.9%,中和沉镓-碱化造液过程镓浸出率为99.5%。
英文摘要:
      The selenium, copper, indium and gallium were comprehensive recovered from the CIGS Scrap by the process which includes sulfatizing roasting, water leaching, copper extraction, indium extraction, gallium neutralization precipitation and alkali leaching. The crude selenium, cathode copper, refined indium and metallic gallium were obtained in the process. The selenium volatilization rate is 99.5% in the Selenium Distillation process under the optimum conditions. The extractions of copper and indium in the solvent extraction are 98.4% and 99.9%, respectively. The leaching rate of gallium can reach 99.5% in the process of gallium neutralization precipitation-alkali leaching.
