Abstract

See full text

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.
