  • Method for producing molybdenum trioxide (MOO.sub.3) from raw materials that contain MOS.sub.2
    Patent number: 5223234
    Abstract: A method and apparatus for producing molybdenum trioxide from raw materials containing molybdenum disulfide including melting the raw materials in an oxidizing atmosphere volatilizing a major portion of the raw materials as molybdenum trioxide with the remainder bonded in a molten slag as MoO.sub.4 and directing an oxidizing gas onto the molten slag to convert the MoO.sub.4 to molybdenum trioxide with the volatilization gas and the gas from the slag being united, the gas cooled and the molybdenum trioxide condensed from the gas into solid form (undesirable admixtures are separated from molybdenum trioxide raw oxides hydrometallurgically).
