Abstract
Provided is a platinum-group metal recovery method for efficiently recovering a platinum-group metal. The method for recovering a platinum-group metal includes an immobilization step of causing a molten product of a raw material containing a platinum-group metal, a molten product of a carbonate or hydroxide of an alkali metal, a molten product of an oxide, and a ceramic material to make contact with each other so as to immobilize the platinum-group metal on the ceramic material.
