Abstract: There is provided a method for recovering PGM, in which at least one base metal oxide selected from a group consisting of copper oxide, iron oxide, tin oxide, nickel oxide and lead oxide is added to and melted in a molten slag, and a PGM alloy contained in the molten slag is recovered.

Abstract: An apparatus for recovering platinum group elements comprises a furnace body having an interior space substantially shot off from external air, a material charging port and an exhaust port provided in an upper half of the furnace body, at least two fluid discharge ports provided in a lower half of the furnace body at different height levels. a material charging chute connected to the material charging port. an exhaust unit connected to the exhaust port; and electrodes for passing electric current through and heating material charged into the furnace. The material charging chute is equipped with a vertical two stage shutter so as to maintain airtightness when material is charged into the interior space of the furnace.

Abstract: A method for recovering platinum group elements comprises charging into a closed electric furnace and melting, together with flux components and a reducing agent, a platinum group element-containing substance to be processed and a copper source material containing copper oxide, sinking molten metal of primarily metallic copper below a molten slag layer of primarily oxides, and enriching the platinum group elements in the molten metal sunk below, and is characterized in that molten slag whose copper content has decreased to 3.0 wt % or less is discharged from the electric furnace and that the copper source material charged into the electric furnace is a granular copper source material of a grain diameter of not less than 0.1 mm and not greater than 10 mm.
