Definition and characteristics
Platinum (Pt) is one of a group of six chemical elements...elements
collectively referred to as the platinum-group elements
(PGE). The other PGEare palladium (Pd), iridium(lr)...ruthenium(Ru). Reference is also
commonly made to platinum-group metals and to platinumgroup minerals, both...to PGM. In this
document we use PGM to refer to platinum-group minerals.
