We examined the distillation process of zinc, lead and cadmium from black ores (the complex sulphide ores) with iron reduction. Zinc, lead and cadmium respectively were presented as a sulphide, -ZnS, PbS or CdS- in the black ores. We obtained Zn, Pb and Cd by reducing the ores with iron powder according to the following reaction:<br/>MS + Fe = M(gas) + FeS M; Zn, Pb and Cd <br/>Each metal was separated making use of their condensation points but the separation of Cd from Zn was very difficult. Still, the metal yield percentages were Zn; 97.5%, Pb; 93.3% and Cd; 90.0% at 1200℃, and at 10^-3 mmHg, and their purities were Zn; 99.1%, and Pb; 98.1% at the same conditions. Optimum conditions were; the reaction temperature 1,200℃, weight ratio of mixture 1 : 1 and the ultimate vacuum 10^-2-10^-3 mmHg.
