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

Processes for the production of platinum group metal (PGM)-enriched alloys are described. The PGM enriched-alloys can have 0 to 60 wt.-% of iron and 20 to 99 wt.-% of one or more PGMs selected from the group consisting of platinum, palladium and rhodium. The described processes exhibit remarkably low PGM losses during production of PGM-enriched alloys therefore yield alloys having considerably high PGM levels.

Process for the production of a PGM-enriched alloy

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.
