description | Disclosed is a method for recovering ruthenium from a solid, wherein a ruthenium compound is supported by a carrier, with good recovery yield. Specifically disclosed is a method for recovering ruthenium, which is characterized by comprising the following steps (1)-(3). Step (1): a step for bringing a solid, wherein a ruthenium compound is supported by a carrier, into contact with a reducing gas, thereby reducing the ruthenium compound Step (2): a step for cooling the solid obtained in the step (1) to 250 DEG C or less in a non-oxidizing gas atmosphere Step (3): a step for mixing the solid obtained in the step (2) with an oxidizing solution, thereby dissolving ruthenium into the solution. |
