a higher temperature and a lower pressure. The calculated suitable temperature range for sulfur recovery in this process is 392-490 K. The Mo content of molybdenum metal ball obtained by experiments is 93.69% and the S content of sulfur products reaches 98.6%. The impurity elements, such as P, S, Cu, As, Pb, Sn, in the molybdenum products are very low. Key words: molybdenum concentrate; vacuum......
