    Abstract:

    Samples of molybdenum sulfide concentrate of Kajaran deposits in Armenia were subjected to oxidation in the atmosphere of water vapor in pilot plant with capacity of 2 kg per hour. It is shown that the rate of sulfur oxidation in the presence of water vapor depends on the reactor temperature, on organization of transport of the reaction products from the surface of treated samples, on the particle size of concentrate and other factors. The optimal process parameters which provide a high degree of molybdenum extraction (98.5%), as well as rhenium (99.6%) and sulfur (98%) in the form of elemental sulfur or sodium sulfide are revealed. The technology is characterized by high environmental safety.

    Keywords:
