PGMs are a mining term. it includes all those elements in that region of the periodic table because they have similar mining properties. they don't have truly minable ores (except Pt, and even that is not very concentrated) and are concentrated from other worked ores. for instance Re is mainly collected from Ni mining.

if there were cheap sources of any of them, they would be more widely used, just because of their myriad uses. Pt and Pd demand are close to world production. other PGMs? economically important curiosities..
