Beschreibung
Zusammenfassung:	A process for converting molybdenum technical oxide into a purified molyb denum trioxide product is provided, generally comprising the steps of: combi ning molybdenum technical oxide with an oxidizing agent and a leaching agent in a reactor under suitable conditions to effectuate the oxidation of resid ual MoS2, MoO2 and other oxidizable molybdenum oxide species to MoO3, as wel l as the leaching of any metal oxide impurities; precipitating the MoO3 spec ies in a suitable crystal form; filtering and drying the crystallized MoO3 p roduct; and recovering and recycling any solubilized molybdenum.
