2.1. Platinum-group element mineralogy

Introduction. The distribution of PGEs (platinum-group elements) in an ore is directly related to the type of ore, which in turn, dictates the mineralogical constitution. PGE ores can be divided into the following main classes (Stribrny et al., 2000): Alluvial ores: These ores contain almost no sulphide and are composed of individual particles ...

Review on the Recovery of the Platinum-Group Metals

Abstract. No definite date can be ascribed to the discovery of platinum; rather it became gradually known to the Western World as a distinct metal of unique properties over a period of two centuries, between 1500 and 1700. The first source to be exploited was the placer deposits in New Granada (now Colombia) where it was initially regarded as a ...
