Recovery of platinum-group metals (PGMs) from spent automotive catalysts: Part I: The primary and secondary sources of PGMs and their use

Abstract

This paper presents a review of the present situation and perspectives in the production of platinum-group metals from primary and secondary sources, as well as in their use. The need and significance of recycling have been highlighted in view of the demand and supply of platinum-group metals. It has been shown that platinum-group metals are mostly used for the manufacture of autocatalysis and that their recycling is important for the conservation of natural resources.
