Abstract

The integrated process of the subject invention is directed to the production of high purity molybdenum chemical products from molybdenum sulfide containing materials by a series of steps, including roasting, sulfuric acid leaching of the calcine to remove impurities from the calcine, ammonia digesting of the calcine to form a pregnant molybdate solution containing dissolved molybdenum, and recovery of the dissolved molybdenum by crystallization and/or molybdic acid precipitation. The process is a 'zero discharge' process in that all process waste streams are combined to produce a ferrous ammonium sulfate fertilizer byproduct.
