With nickel removal solution after copper electrolysis taken to be a substitute for sulfuric acid as the leaching agent, a processing technique consisting of oxygen pressure acid leaching, evaporative crystallization and reduction by SO2 was adopted to realize utilization of arsenic matte resource. The results show that with sulfuric acid concentration at 120 g/L, leaching temperature of 120 ℃, oxygen partial pressure of 0.8 MPa, liquid-solid ratio of 7∶1 and leaching time of 2 h, the leaching rates of copper, arsenic and antimony from arsenic matte can reach 97.99%, 94.68% and 17.28%, respectively, showing an efficient leaching of copper and arsenic from matte copper and selective separation of antimony can be actualized. The solution obtained from pressure acid leaching was then subjected to vacuum evaporation followed by natural cooling for crystallization, leading to the precipitation of copper sulfate. And then reduction by SO2 was adopted to prepare arsenic trioxid using mother liquor, leading to the obtained copper sulfate with purity up to 98.12% and the obtained arsenic trioxide with purity up to 99.49%.

以铜电解脱镍后液替代硫酸作为浸出剂,采用氧压酸浸-蒸发结晶-SO2还原工艺实现砷冰铜资源化利用。结果表明,在硫酸浓度120 g/L、浸出温度120 ℃、氧压0.8 MPa、液固比7∶1、浸出时间2 h条件下,砷冰铜中铜、砷、锑浸出率分别为97.99%、94.68%、17.28%,实现了高效浸出冰铜中铜、砷和选择性分离锑;氧浸液采用真空蒸发-自然冷却结晶析出硫酸铜,结晶母液采用SO2还原工艺制取三氧化二砷,得到的硫酸铜(以CuSO4·5H2O计)纯度可达98.12%,三氧化二砷纯度达到99.49%。

以铜电解脱镍后液替代硫酸作为浸出剂,采用氧压酸浸-蒸发结晶-SO2还原工艺实现砷冰铜资源化利用。结果表明,在硫酸浓度120 g/L、浸出温度120 ℃、氧压0.8 MPa、液固比7∶1、浸出时间2 h条件下,砷冰铜中铜、砷、锑浸出率分别为97.99%、94.68%、17.28%,实现了高效浸出冰铜中铜、砷和选择性分离锑;氧浸液采用真空蒸发-自然冷却结晶析出硫酸铜,结晶母液采用SO2还原工艺制取三氧化二砷,得到的硫酸铜(以CuSO4·5H2O计)纯度可达98.12%,三氧化二砷纯度达到99.49%。

With nickel removal solution after copper electrolysis taken to be a substitute for sulfuric acid as the leaching agent, a processing technique consisting of oxygen pressure acid leaching, evaporative crystallization and reduction by SO2 was adopted to realize utilization of arsenic matte resource. The results show that with sulfuric acid concentration at 120 g/L, leaching temperature of 120 ℃, oxygen partial pressure of 0.8 MPa, liquid-solid ratio of 7∶1 and leaching time of 2 h, the leaching rates of copper, arsenic and antimony from arsenic matte can reach 97.99%, 94.68% and 17.28%, respectively, showing an efficient leaching of copper and arsenic from matte copper and selective separation of antimony can be actualized. The solution obtained from pressure acid leaching was then subjected to vacuum evaporation followed by natural cooling for crystallization, leading to the precipitation of copper sulfate. And then reduction by SO2 was adopted to prepare arsenic trioxid using mother liquor, leading to the obtained copper sulfate with purity up to 98.12% and the obtained arsenic trioxide with purity up to 99.49%.
