PURIFICATION OF MOLYBDENUM TECHNICAL OXIDE

摘要

A process for converting molybdenum technical oxide into a purified molybdenum trioxide product is provided, generally comprising the steps of: combining molybdenum technical oxide with an oxidizing agent and a leaching agent in a reactor under suitable conditions to effectuate the oxidation of residual MoS<SUB>2</SUB>, MoO<SUB>2</SUB> and other oxidizable molybdenum oxide species to MoO<SUB>3</SUB>, as well as the leaching of any metal oxide impurities; precipitating the MoO<SUB>3</SUB> species in a suitable crystal form; filtering and drying the crystallized MoO<SUB>3</SUB> product; and recovering and recycling any solubilized molybdenum.
