Combined method for processing molybdenite concentrates based on firing with sodium carbonate

V. A. Imideev, A. O. Berbenev, П. В. Александров

Abstract

The article describes a perspective combined method of treatment molybdenite concentrate based on roasting with sodium carbonate and following water leaching process. This method is characterized by almost completely binding of the sulfur compounds into water-soluble sodium sulfate, conversion of molybdenite into water-soluble odium molybdate, and if concentrate contains rhenium - transform into water-soluble sodium perrhenate.
