Abstract
A looping method for production of MoO, the method including reacting molybdenite feed with a substantially stoichiometric mixture comprising MoOand oxygen in a first furnace to produce MoOand SO, removing a first portion of the MoOfrom the first furnace, transferring a second portion of the MoOfrom the first furnace to a second furnace, reoxidizing of the transferred portion of the MoOin the second furnace to MoO; and looping the MoOfrom the second furnace to the first furnace for use as an oxidizing agent.
