摘要

采用微波加热技术对铜阳极泥进行硫酸化焙烧脱硒处理。通过响应曲面法优化工艺条件,探究了微波焙烧温度、焙烧时间和酸泥比对铜阳极泥脱硒率的影响,建立了微波硫酸化焙烧铜阳极泥脱硒工艺的二次回归模型。回归分析结果表明,酸泥比、微波焙烧时间对脱硒率影响显著。优化工艺条件为:酸泥比0.9:1,微波焙烧时间28min、焙烧温度400℃,在此工艺条件下,脱硒率模型预测值为95.35%,与实验值96.12%相近。响应曲面法优化设计有效。
        Copper anode slime removals selenium by microwave heating technology sulfuric acid roasting.Optimizing the process conditions by response surface method,the effects of microwave roasting temperature,roasting time and acid mud ratio on the selenium removal rate of copper anode slime were investigated,and two regression models were established for the removal of selenium from copper anode mud by microwave sulfuric acid roasting.The results of regression analysis showed that acid ratio and microwave roasting time had a significant effect on selenium removal rate.The optimum process conditions are:acid ratio 0.9:1,microwave roasting time 28 min,roasting temperature 400 ℃.Under this condition,the theoretical removal ratio is 95.35%,which is similar to the experimental value of 96.12%,which proves that the optimal design is effective by the response surface method.
