| 摘 要： | 研究一项针对镍钼矿用高压酸浸的方法回收镍和钼的全湿法工艺。采用该工艺避免了传统上艺焙烧镍钼矿（15％～25％s）带来的人量S02和As2O3排放，减小了对环境的污染；与现有的湿法碱浸回收钼工艺相比，本工艺存酸浸过程中回收了儿乎全部的镍和人部分的钼。在氧压环境下，几乎全部的镍和大部分的钼都进入溶液，少部分的钼留在酸浸渣中，睃浸渣进一步用碱（NaOH）浸出。在最佳的实验条件下，97％的镍和96％的钼分别被浸出。

| Abstract: | A direct hydrometallurgical route for nickel and molybdenum extraction from a nickel-molybdenum （Ni-Mo） ore using pressure acid leaching was studied. The nickel and molybdenum were extracted by acid leaching under oxygen pressure. Compared with traditional roasting methods, this hydrometallurgical method eliminates SO2 and As203 emission （the Ni-Mo ore containing 15%-25% S）. Compared with existing alkali leaching recovery of molybdenum process, almost all the nickel and considerable molybdenum were extracted in the acid leaching process. Under oxygen pressure conditions, almost all the nickel and a substantial part of the molybdenum were dissolved into the acid leaching liquor and the other part of the molybdenum was left in the acid leach residue. The acid leach residue was further leached under alkaline （NaOH） conditions. Under optimal experimental conditions, the extraction rates nickel and molybdenum reached 97% and 96%, respectively. |
