| 摘 要： | 硫化锌精矿氧压浸出工艺生产实践表明,如果没有严格控制氧压浸出过程中硫组元的酸化程度,将造成锌冶炼系统的酸过量问题,进而影响各项技术经济指标。针对氧压浸出系统容易出现酸根过高的现象,探索氧压浸出工艺中二段终酸浓度、反应温度、氧分压及浸出时间对硫组元的酸化效果和锌浸出的影响,在较优的工艺条件下,锌浸出率高达98%以上,硫酸化率仅10%左右。

| Abstract: | Production practice of oxygen pressure leaching process for zinc sulfide concentrates showed that if sulfation degree of sulfur components is not strictly controlled, acid expansion of zinc smelting system will occur and technical and economic indexes will be affected. To address phenomenon of high acid radical in oxygen pressure leaching system, effects of final acid concentration of second stage, reaction temperature, oxygen partial pressure and leaching time on acidification of sulfur components and zinc leaching rate in oxygen pressure leaching process are explored. Zinc leaching rate is 98% above and sulfation rate is only about 10% under the optimum cal conditions. |
