摘要

银-铜-锑系统是铅阳极泥的关键成分,具有极高的经济回收价值。本文首次采用分子相互作用体积模型(MIVM)、修正分子相互作用体积模型(M-MIVM)、威尔逊方程、Miedema 模型、正则表达式模型(RSE)和亚正则表达式模型(SRSE)等六种模型计算了银铜锑二元合金的活性预测值及其与实验数据的偏差。结果表明,M-MIVM 的平均相对偏差和平均标准偏差的总体均值分别为 0.01501 和 3.97278%,比其他五个模型小约 2 至 6 倍,表明 M-MIVM 的稳定性和可靠性。同时,M-MIVM 计算出的 1423 K 时铜银二元合金、1250 K 时锑银二元合金和 1375 K 时锑铜二元合金的预测数据更加可靠,并通过了 Herington 试验。然后,根据 M-MIVM 和真空理论绘制了 Cu-Ag、Sb-Ag 和 Sb-Cu 二元合金的分离系数-组分 (β-x)、温度-组分 (T-x-y) 和压力-组分 (P-x-y),结果表明 Cu-Ag 二元合金相对较难分离,高温或高铜含量不利于获得高纯度银。同时,T-x-y 图的理论数据与现有的实验数据一致。这些结果可以指导有关银-铜、银-锑和铜-锑二元合金的真空分离实验和工业生产。

Activity Calculation and Vacuum Separation Theoretical Research concerning Ag–Cu, Ag–Sb and Cu–Sb Binary Alloys
The Ag–Cu–Sb system is a key component of lead anode slime and boasts an exceptionally high economic recovery value. In this work, six models, including the Molecular Interaction Volume Model (MIVM), Modified Molecular Interaction Volume Model (M-MIVM), Wilson equation, Miedema model, Regular Solution Model (RSE) and Sub-Regular Solution Model (SRSE), are used to calculate the predicted values of the activity and its deviations with experimental data for binary alloys in the Ag–Cu–Sb system for the first time. The result reveals that the overall means of the average relative deviation and average standard deviation of the M-MIVM are 0.01501 and 3.97278%, respectively, which are about two to six times smaller than those of the other five models, indicating the stability and reliability of the M-MIVM. In the meantime, the predicted data of the Cu–Ag binary alloy at 1423 K, Sb–Ag binary alloy at 1250 K and Sb–Cu binary alloy at 1375 K calculated from the M-MIVM are more reliable and pass the Herington test. Then, the separation coefficient–composition (β–x), temperature–composition (T–x–y) and pressure–composition (P–x–y) of the Cu–Ag, Sb–Ag and Sb–Cu binary alloys are plotted based on the M-MIVM and vacuum theories, showing that the Cu–Ag binary alloy is relatively difficult to separate and that high temperatures or high copper contents are detrimental to obtaining high-purity silver. Meanwhile, theoretical data of the T–x–y diagram are consistent with the available experimental data. These results can guide vacuum separation experiments and industrial production concerning Ag–Cu, Ag–Sb and Cu–Sb binary alloys.
