A process for the recovery of precious metal (PM) from PM oil, the process including combustion of PM oil within a furnace, where the PM oil is burned in atomized form.

Process for the recovery of precious metal from petrochemical process residues

A process for the incineration of activated coal-supported PGM catalysts, the process comprising a joint incineration of a multilayer arrangement, wherein the multilayer arrangement includes (i) a top layer of particulate activated coal-supported PGM catalyst, (ii) a layer of coarse charcoal located beneath said top layer and, optionally, (iii) a layer of particulate coke located beneath the charcoal layer, and wherein an upward flow of oxidizing gas is homogeneously passed through said multilayer arrangement during the incineration.

A process for production of a PGM (platinum group metal)-enriched alloy containing iron and PGM(s) (platinum, palladium and/or rhodium) includes steps of: (1) providing a sulfur-free PGM collector alloy, (2) providing a copper- and sulfur-free material capable of forming a molten slag-type composition including silicon dioxide and magnesium and/or calcium oxide, (3) melting the PGM collector alloy and slag-forming material within a converter until a multi-phase system of a lower high-density molten mass of PGM collector alloy and an upper low-density molten mass of slag-type composition has formed, (4) contacting an oxidizing gas with the lower high-density molten mass of step (3) until conversion of the PGM collector alloy into a PGM-enriched alloy, (5) separating an upper molten slag formed in step (4) from the PGM-enriched alloy by difference in density, (6) allowing the separated molten masses to cool down and solidify, and (7) collecting the solidified PGM-enriched alloy.
