昆明工学院冶金系真空冶金实验室在1975年试验的基础上,又对锡—砷—铅合金(炭渣)真空蒸馏进行了小型试验和扩大试验,一次实验的试料量由10克作到4000克,经过60余次试验,获得如下成效:挥发率:砷97%,铅99%;产品:同时得到三种,质最分别为:粗锡97%Sn,粗砷80～90%As,粗铅88%Pb;

Kunming Institute of Metallurgy Department of Vacuum Metallurgy Laboratory in 1975 on the basis of the experiment, but also on the tin - arsenic - lead alloy (carbon residue) vacuum distillation conducted a small test and the expansion of the test sample volume from 10 grams 4000 grams, after more than 60 tests, the following results were obtained: Volatilization rate: 97% of arsenic, 99% of lead; Products: At the same time, Crude lead 88% Pb;
