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.

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.

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.
