| 摘 要： | 金川镍矿浮选尾矿数量巨大,含有相当可观的有价金属,其中有价金属的回收受到越来越多的关注。金川老尾矿库尾矿砂中Ni和Cu赋存状态复杂,水溶性矿物态、可交换离子态、碳酸盐态、结晶度较差的Fe氧化物态、结晶度较好的Fe氧化物态、硫化物态和残渣态中都含有数量不等的有价金属Ni和Cu;尾矿砂风化作用释放的金属阳离子大多数在发生氧化的硫化物位置原位发生水解沉淀形成次生矿物,有价金属Ni和Cu在尾矿库中没有发生明显的富集。金川镍矿尾矿砂中Ni和Cu适于用化学酸溶浸出的方法进行二次回收。

| Abstract: | Because tailings of Jinchuan nickel mine are of large quantities and contain considerable valuable metals, the recovery of valuable metals from them have aroused more and more attention. Investigations reveal that the modes of occurrence of Ni and Cu are complicated in old flotation tailings, and they occur in different amounts in all the phases of water soluble fraction, exchangeable fraction, carbonate fraction, poorly crystalline Fe oxide fraction, good crystalline Fe oxide fraction, sulfide fraction and silicate fraction. The metal ions released from metal sulfide oxidation are mainly precipitated and adsorbed in situ and not concentrated in tailings. The acid leaching is more appropriate for the recovery of Ni and Cu from the flotation tailings of Jinchuan nickel mine. |
