摘要:
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.

A method for recovering platinum group elements comprises charging an oxide raw material entraining platinum group elements, copper oxide, solid carbonaceous reducing agent and flux into a closed electric furnace equipped with at least one electrode for heating material and a roof for substantially shielding material charged into the furnace from the exterior atmosphere. The charged material is melted and reduced to form a layer of molten metal under a molten slag layer and enrich platinum group elements in this molten metal. The oxide raw material, copper oxide, solid carbonaceous reducing agent and flux are prepared as powdery or particulate materials, premixed and then charged into the electric furnace. The heat-melted material in the furnace is allowed to stand at a temperature of 1200° to 1500° C. for at least 5 hours, with the molten metal containing platinum group elements then being discharged outside the furnace.
摘要:
Cermet material obtained from unused inert anodes, used inert anodes and cermet used in the production of inert anodes is beneficiated into a nonferrous metal concentrate composition from which metal values contained in the composition may be readily recovered by using a conventional smelting process. The invention also relates to the use of the composition in a smelting process for the recovery of metal values from the cermet composition of the invention.
