A method of suppressing a distribution of PGM into a Cu2O slag in an oxidation smelting of a method of recovering PGM, is provided, including: carrying out reduction smelting to a treatment target member containing PGM, Cu and/or Cu2O, and flux, to thereby generate a molten slag and a Cu alloy containing PGM; and oxidizing and melting the Cu alloy containing the PGM, to thereby generate a Cu2O slag containing PGM and the Cu alloy, with more concentrated PGM concentration than the Cu alloy containing the PGM, wherein when carrying out the oxidation smelting, acidic oxide or basic oxide is added. |
