Abstract: A method for recovering a valuable substance is provided. The method includes: a thermal treatment step of thermally treating a target containing a valuable substance while supporting a target storing unit, in which the target is stored, by a supporting unit that can support the target storing unit, wherein the thermally treating includes heating a gas present in a region, in which the supporting unit is positioned, by a flame for thermally treating the target such that the target storing unit is not contacted by the flame; and a valuable substance recovering step of recovering the valuable substance from a thermally treated product of the target obtained in the thermal treatment step.
