Abstract 1. A PROCESS FOR PRUDUCING A HIGH PURITY MOLBDENUM PRODUCT WHICH COMPRISES THE STEPS OF EXTRACTING A MOLYBDENITE ORE PRODUCE A PARTICULATED CENCENTRATE HAVING AN AVERAGE PARTICLE SIZE OF LESS THAN ABOUT 200 MESH AND CONSISTING PREDOMINANTLY OF MOS2, OXIDIZING SAID CONCENTRATE TO CONVERT SUBSTANTIALLY ALL THE MOS2 TO MOLYBDENUM OXIDE, CONTACTING THE OXIDIZED SAID CONCENTRATE WITH AN AQUEOUS LEACH SOLUTION AT A TEMPERATURE RANGING FROM ABOUT 10* C. UP TO 100* C. FORMING A SLURRY CONTAINING UP TO ABOUT 50% SOLIDS FOR A PERIOD OF TIME SUFFICIENT TO EXTRACT AT LEAST A PORTION OF THE CONTAMINATING METALS INCLUDING COPPER, POTASSIUM, MAGNESIUM, ALUMINUM, SODIUM AND IRON FROM SAID CONCENTRATE, CONTACTING SAID AQUEOUS LEACH SOLUTION WITH A CATION EXCHANGE RESIN FOR ADSORBING THE EXTRACTED SAID CONTAMINATING METALS FROM SAID SOLUTION IN THE FORM OF A LOADING ON SAID RESIN, SEPARATING THE AQUEOUS LEACHED SAID CONCENTRATE FROM THE LOADED SAID RESIN AND SAID AQUEOUS LEACH SOLUTION, CONTACTING THE SEPARATED SAID CONCENTRATE WITH AN AQUEOUS AMMONIACAL LEACH SOLUTION AT A TEMPERATURE RANGING FROM ABOUT 25* C. UP TO ABOUT 100* C. AND CONTAINING ABOUT 5% TO ABOUT 30% AMMONIA FOR A PERIOD OF TIME SUFFICIENT TO CONVERT SUBSTANTIALLY ALL OF SAID MOLYBDENUM OXIDE THEREIN TO A SOLUBLE AMMONIUM MOLYBDATE COMPOUND, SEPARATING THE REMAINING SOLID RESIDUE FROM SAID AMMONIACAL LEACH SOLUTION AND THEREAFTER CRYSTALLIZING SAID SOLUTION AND RECOVERING A HIGH PURITY AMMONIUM MOLYBDATE PRODUCT.
