铅锑合金真空蒸馏分离的研究,通过热力学计算、小型试验和扩大试验对含 Sb≤90%含 Pb9～10%的铅锑合金在真空度为99Pa、温度为700～750℃的条件下,采用多级连续真空蒸馏可以一次获得含 Sb>99%的产品锑,含 Pb50～60%占总进料量的10～15%的铅锑合金返回粗合金处理工序。 Lead-antimony alloy vacuum distillation separation studies, through the thermodynamic calculations, small-scale experiments and the expansion test for Pb ≤ 9% Pb ≤ 9% Pb-Sb alloys with a vacuum degree of 99Pa, the temperature of 700 ~ 750 ℃ ​​under the conditions of Multi-level continuous vacuum distillation can be obtained once containing Sb> 99% of the product antimony, containing Pb 50 ~ 60% of the total amount of feed 10 ~ 15% lead-antimony alloy back to the crude alloy processing steps.
