What is it about?

This paper considers the potential for economic exploitation of platinum-group elements from the oxidized near-surface environment. Both the mineral form that such mineralization might take, as well as potential routes for chemical or physical concentration of the mineralization are considered.

Why is it important?

The platinum-group elements are vital for modern life but are very localized and rare in the earth's crust. Up till now, the vast majority of platinum-group elements extracted have come from a limited number of deep, sulphide-associated orebodies in South Africa, Russia and Canada. It has become important to diversify the sources of such strategic raw materials and this paper considers the practicality of this diversification.


Laboratory work on the stability of oxidized PGE mineralization was carried out at Imperial College and the Natural History Museum, London.
