| Abstract: | In this paper, the technical parameters and mechanism of recovery process of Selenium from copper anode slime by vacuum distillation were investigated. This paper analyzes the diffusion of the selenium in the melts, evaporation on the melts surface, spatial diffusion of gas in the vacuum furnace and the condensation of selenium gas. According to the result analysis of vacuum distillation, the optimal conditions are obtained as following： 330℃, 30 min and 10 Pa in furnace. The purity of selenium prepared according to this method was 99.9 %. |
