| 摘 要： | 以硫酸为浸出介质，通过响应面方法和Box-Behnken设计（BBD）对浸出条件，包括酸浓度、液固比和温度进行优化。结果表明，酸浓度是最重要的因素，其次是温度和液固比。通过响应面优化，确定在酸浓度为116.77 g/L，液固比为8，温度为170℃的较佳工艺条件下，铜转炉灰中砷的提取率达到94.49%，说明响应面方法可以成功优化铅转炉砷灰的酸提取实验。

| Abstract: | Sulfuric acid was used as the leaching medium, and the leaching conditions, including acid concentration, liquid-solid ratio and temperature, were optimized by response surface methodology and Box-Behnken design (BBD). The results showed that the acid concentration was the most important factor, followed by temperature and liquid-solid ratio. Through response surface optimization, the optimal process conditions were determined as follows: acid concentration of 116.77 g/L, liquid-solid ratio of 8, and temperature of 170℃. Under these conditions, the arsenic extraction rate of copper converter reached 94.49%, indicating that the acid extraction experiment of lead converter arsenic ash could be successfully optimized by response surface methodology. |
