【摘要】：采用加压酸浸方法对铜阳极泥脱除铜、碲工艺开展研究。考察了反应总压、温度、时间及初始酸度对铜、碲脱除效果的影响。结果表明,在压力1.0 MPa、温度140℃、反应时间2h、初始酸度120g/L的较优条件下,铜脱除率达97.71%,碲脱除率达59.62%,金、银基本无损失。
[Abstract]:The technology of copper removal and tellurium removal from copper anode slime by acid leaching under pressure was studied. The effects of total pressure, temperature, time and initial acidity on the removal of copper and tellurium were investigated. The results show that under the optimum conditions of pressure 1.0 MPA, temperature 140 鈩，
