A method for recovering a valuable substance, the method comprising:
- thermally treating a target at 750° C. or higher and lower than 1,085° C., the target containing a valuable substance and is stored in a target storage, via a flame blocker that is separate from the target storage and provides a barrier that is configured to block a flame that is directed at the flame blocker for thermally treating the target such that the target storage is not contacted by the flame;
- and
- recovering the valuable substance from a thermally treated product of the target obtained in the thermally treating.
