  • METHOD AND MEANS FOR USING MICROWAVE ENERGY TO OXIDIZE SULFIDIC COPPER ORE INTO A PRESCRIBED OXIDE-SULFATE PRODUCT
    Publication number: 20080118421
    Abstract: The present invention is directed to the microwave treatment of a class of selected metal ores and concentrates, particularly those known as chalcopyrite, in a fluidized bed reactor. The end product is commonly a mixture of copper oxide and copper sulfate, both of which are liquid soluble and directly recoverable by known techniques. The ratio of the oxide-sulfate mixture end product may be controlled by suitable control of microwave parameters.

  • METHOD FOR OXIDIZING CARBONACEOUS ORES TO FACILITATE PRECIOUS METAL RECOVERY
    Publication number: 20080069723
    Abstract: A method of oxidizing carbonaceous ores to assist in the recovery of metals is provided. The method includes the steps of heating a bed of carbonaceous ore in the reaction chamber of a reactor vessel, using microwave energy to initiate and sustain oxidation of the carbonaceous ore within the bed into carbon dioxide, controlling the inflow of oxygen into the reaction chamber to provide sufficient oxygen to maintain the reaction C+O2?CO2, and monitoring the depletion of carbon from the carbonaceous ore.

  • METHOD AND APPARATUS FOR MICROWAVE INDUCED PYROLYSIS OF ARSENICAL ORES AND ORE CONCENTRATES
    Publication number: 20080069746
    Abstract: A method is provided that includes the steps of passing microwave energy through a sulfidic material comprising arsenopyrite and pyrite to reduce at least most of the arsenopyrite to arsenic sulfide and form a calcine, the material being positioned in a reaction chamber of a reactor vessel and removing the arsenic sulfide from the calcine.
