| 摘 要： | 本工作研究了在含氰基咪唑类离子液体中从辉铜矿中提取铜．通过X-射线衍射仪和JSM-5600LV扫描电镜对产物进行了表征．实验结果表明：辉铜矿Cu（I）的溶解是离子液体中的氰基和酸共同作用结果．本实验体系采用N-氰乙基-N’-正丁基咪唑四氟硼酸盐，是通过增大空间位阻适度降低Cu（J）与氰基的配位作用，利于氧化亚铜和铜的制备．

| Abstract: | Preparation of nanometer copper from chalcocite with nitrile imidazole ionic liquids（IL） system and characterization of products by X - ray diffraction （XRD） and JSM - 5600LV scanning electron micro- scope （SEM） were studied. The experiment showed that the dissolution of the Cu（I） in ehalcocite was effect of the nitrile together with acid in IL. The experiment system were N - acetonitrile - N＇ - n - butyl imidazole four fluorin borate, which had larger space volume reducing complex of Cu （I） and nitrile and benefiting to the preparation of Cu2O and Cu. |
