Abstract:

A new method for integrated processing of molybdenum sulfide concentrates by hydrogen reduction was elaborated. It allowed high degree of extraction of major components of the concentrate: molybdenum (98.5%), rhenium (96%), and full recovery of sulfur (about 98%) from the gas phase in the form of sodium sulfide, which is a necessary reactant for the enrichment of copper and molybdenum ores.
The studies were conducted using Kajaran (Armenia) molybdenum sulfide concentrate. The kinetic and thermodynamic parameters of the process were obtained. The optimal operation regimes were found experimentally on the enlarged laboratory setup. It was shown that the technology is environment-friendly.
