Sulfide-poor deposits of platinum-group elements (PGE) occur in two main types: silicate-type and oxide-type. In the silicate-type mineralization PGE form discrete platinum-group minerals (PGM) that occur as inclusions in various silicate minerals.

In the oxide-type mi neralization PGM may have different modes of occurre nce.

Coal is valued for its energy content, and, since the s, has been widely used to generate electricity. Chamberlain and Pojar, and Wincup et al.,disclose limited examples of in situ precious metals mining operations.

However, the technology of these operations cannot be used to recover most of the remaining U.S. precious metal reserves and resources, mainly because of environmental concerns associated with conventional lixiviants.

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 () and Lorand et al. 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.5/5(1).
