The reason for the extreme depletion of the platinum group elements PGE in the silicate Earth is the topic of the articles in this issue by Palme 2008 and Lorand et al. 2008. In this article we examine the ways in which that extreme depletion can be undone to the extent that we can mine and extract the PGE for practical uses.

1. Introduction. Based on the high partition coefficients of the platinum group elements PGE between silicate and base metal sulfide liquid, and the presence of a small quantity of base metal sulfide minerals BMS in most PGE ore deposits, models for the formation of these ores suggest that the PGE were collected from mafic silicate magma by base metal sulfide liquid e.g. Naldrett, 2004.
