Recovery Technology of Platinum Group Metals

Abstract

Platinum group metals (PGMs) are indispensable materials for the automotive catalyst as these metals have excellent catalytic properties. However, these metals have serious problems in terms of resource security. This is because the production amount is limited, and moreover the primary supply of the metals is restricted to the mines located in certain countries. In this article, current status of PGMs is reviewed, and recent topics on recycling technologies for recovering PGMs from the surface of the scraps are introduced.
