METHOD FOR RECOVERING METAL FROM UNUTILIZED RESOURCE, AND APPARATUS FOR RECOVERING METAL

摘要

PPROBLEM TO BE SOLVED: To provide a method for recovering a metal from unutilized resources, which can easily and rapidly recover the metal with high purity from the unutilized resources which have not been conventionally utilized effectively, and to provide an apparatus for recovering the metal. PSOLUTION: The apparatus 1 for recovering the metal such as nickel Ni from petroleum-based unutilized resources such as petroleum coke P includes: a metal-volatilizing furnace 4 which volatilizes nickel Ni that is combined with an organic substance included in the petroleum coke P in a reductive atmosphere containing introduced water vapor to gasify the nickel; a gas-refining section 5 which cools the gas Ga that has been generated in the metal-volatilizing furnace 4 to enable the nickel Ni to be recovered; and a partial oxidation furnace 8 which partially oxidizes nickel Ni that has not been gasified in the reductive atmosphere.
