    摘要: This invention provides a fine particle composite comprising fine powder of a sulfide or sulfide complex comprising a given element. The fine particle composite is obtained by a method for producing a fine particle composite comprising fine powder of a sulfide or sulfide complex comprising at least one element selected from the group consisting of molybdenum (Mo), rhodium (Rh), ruthenium (Ru), and rhenium (Re). Such method comprises steps of: preparing a solvent mixture from at least one compound containing an element selected from among molybdenum (Mo), rhodium (Rh), ruthenium (Ru), rhenium (Re), and sulfur (S); and subjecting the solvent mixture to a hydrothermal or solvothermal reaction. The resulting fine particle composite comprises fine particles of a sulfide or sulfide complex comprising at least one element selected from the group consisting of molybdenum (Mo), rhodium (Rh), ruthenium (Ru), and rhenium (Re).

    摘要: There is provided a hydrometallurgical process of recovering rhenium values from mixtures thereof with other metal values in which the rhenium values constitute a minority amount, for example super-alloys, which comprises subjecting the mixture to strongly oxidizing acid conditions, preferably an aqueous mixture of hydrochloric acid and nitric acid, so as to form perrhenate species of at least the major proportion of the rhenium values in the mixture, dissolving the perrhenate species and other soluble metal species in aqueous solution, removing insoluble metal species from the aqueous solution, and isolating the rhenium species from the solution.
