SULFIDE OXIDATION PROCESS FOR PRODUCTION OF MOLYBDENUM OXIDES FROM MOLYBDENITE

摘要

A looping method for production of MoO₂, the method including reacting molybdenite feed with a substantially stoichiometric mixture comprising MoO₃ and oxygen in a first furnace to produce MoO₂ and SO₂, removing a first portion of the MoO₂ from the first furnace, transferring a second portion of the MoO₂ from the first furnace to a second furnace, reoxidizing of the transferred portion of the MoO₂ in the second furnace to MoO₃; and looping the MoO₃ from the second furnace to the first furnace for use as an oxidizing agent.
