Abstract. The formation of ore deposits of the platinum-group elements (PGE) requires that their concentrations be raised about four orders of magnitude above typical continental crustal abundances. Such extreme enrichment relies principally on the extraction capacity of sulfide liquid, which sequesters the PGE from silicate magmas.

Summary. The six elements of the platinum group – ruthenium, rhodium, palladium, osmium, iridium and platinum – are referred as platinum-group metals (PGM). Enrichment of PGM occurs in deposits of several types developed in a limited range of geological settings, commonly associated with nickel and copper. Underground …
