A Review of the Behaviour of Platinum Group Elements

The largest and most significant type of geological deposit of platinum group elements (PGEs) is that associated with magmatic base metal sulfide minerals in layered mafic or ultramafic igneous intrusions. The common association of PGEs with sulfide minerals is a result of processes of magmatic and sulfide liquid segregation and fractionation.

History of PGM PMM

In the 18th century platinum was a tough challenge to European scientists trying to understand and use the metal. Their difficulties came from the very properties which make platinum suitable for so many applications, such as its high melting point and its great resistance to corrosion. The problems were compounded by the other metals of the platinum group, which were present in raw platinum
