Abstract
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.
