从理论和实验两方面研究真空蒸馏分离三元锡铅锑合金的可能性,采用正交实验方法研究蒸馏温度、蒸馏时间和料层厚度三大因素对高锑锡铅锑三元合金（Sb26.07%）分离效果的影响,并探究了最佳分离条件。结果表明：对分离效果影响大小依次为蒸馏温度、蒸馏时间、物料质量,实现高锑锡铅锑三元合金高效分离的最佳条件是蒸馏温度1200℃、蒸馏时间25min、料层厚度6.6 mm。

英文摘要：

The feasibility of extraction of Sn from ternary Sn-Pb-Sb alloy by vacuum distillation, a novel environmen- tal friendly technique, was theoretically analyzedand experimentally studied. The impacts of the vacuum distillation condi- tions, including the distillation temperature and time, pressure, and alloy mass and contents, on direct recovery rate of tin from ternary alloy（Sb 26.07 % ）were investigated in orthogonal experimental design. The contents in slag were character- ized. The preliminary results show that three factors significantly affect the separation rate of Sn, and their impacts are list- ed in a descending order： distillation temperature, distillation time, and alloy mass. The optimized distillation conditions include a distillation temperature of 1200℃, a distillation time for 25 min. and a Sn-Pb-Sb alloy thickness of 6.6 mm.
