Abstract With the development of high-tech fields, high purification of metal manganese has become an inevitable trend in the development of the industry. In this study, using electrolytic manganese as raw material, through self-developed high-efficiency distillation furnace, the high-purity manganese with a purity of more than 4N5 was prepared in one step combined with partition condensation, the length of the main metal condensation zone was extended by setting a constant temperature condensation section in the condensation zone to achieve the purpose of improving the metal yield. The theory of vacuum distillation of electrolytic manganese was analyzed, and the effects of different distillation temperatures and times on the volatilization rate and the temperature of the constant temperature condensation section (condensation temperature) on the metal yield were studied. At the same time, the impurity content in the condensed manganese at different distillation temperatures was detected by inductively coupled plasma mass spectrometry (ICP-MS). The results show that the main metal Mn is easy to separate from the impurity metal at the selected distillation temperature, but the higher the temperature, the weaker the separation ability. With the increase of distillation temperature and holding time, the volatilization rate increases. Setting the main metal constant temperature condensation section can greatly improve the me-tal yield, with the increase of condensation temperature, the metal yield increases first and then decreases. With the increase of distillation temperature, the contents of Cd, K, Na, and Zn in condensed manganese are almost unchanged, while the contents of Mg, Ca, Pb, Cu, Cr, Ni, Fe, and Co increased with the increase of distillation temperature. Considering comprehensively, high-purity manganese with the purity of 4N5 can be obtained under a system pressure of 10^-3—10^-2 Pa, a condensation temperature of 1 100 ℃, a holding time of 90 min, and a distillation temperature of 1 400 ℃. In this instance, the volatilization rate is 86.94%, and the yield can reach 94.32%.
