【摘要】 本文基于热力学分析及X射线衍射（XRD）、扫描电子显微镜（SEM）和能谱分析（EDS）等表征方法，对某铜冶炼企业阳极泥进行了预处理脱铜研究，探讨了氧压酸浸工艺参数对铜、硒、碲浸出效果的影响.实验结果表明：随着浸出酸度、温度、压力、液固比的提高，铜、硒、碲的浸出率均提高；浸出时间的延长对铜、硒、碲浸出率的提高有限.当控制溶液中硫酸质量浓度为80 g/L，浸出温度为140℃，浸出压力为0.8 MPa，浸出时间为60 min，浸出液固比为2时，铜、硒、碲的浸出率分别为93%,14%和45%.本文研究可为铜冶炼企业阳极泥预处理工艺中，避免硒、碲分散或通过强化浸出条件提高硒、碲浸出率提供参考.更多还原

【Abstract】 Based on the thermodynamic analysis and characterization methods such as X-ray diffraction(XRD), scanning electron microscopy(SEM), and energy dispersive spectroscopy(EDS), a study on the de-coppering from anode slime for a copper smelting enterprise was conducted, and the leaching effect of copper, selenium, and tellurium during the oxygen pressure acid leaching process was studied. The experimental results show that the leaching rates of copper, selenium, and tellurium are improved with the increase of leaching acidity, temperature, pressure, and liquid-to-solid ratio; the extension of leaching time has a limited influence on improving the leaching rates of copper, selenium, and tellurium. When the sulfuric acid mass concentration in the solution is controlled at 80 g/L, the leaching temperature at 140 ℃, the leaching pressure at 0. 8 MPa, the leaching time at 60 min, and the liquid-to-solid ratio at 2, the leaching rates of copper, selenium, and tellurium are 93%, 14%, and 45%, respectively. A reference is provided for copper smelting enterprises to avoid the dispersion of selenium and tellurium or to enhance leaching conditions to improve the leaching rates of selenium and tellurium during the anode slime pretreatment process.更多还原
