Platinum Group Metals (PGM),which have high melting temperatures and high chemical durability, are being widely used as electronic materials, catalyst, etc. It is important to develop their recycling processes in order to utilize the urban mine in our sustainable society. In high temperature extractive processes with slag treatment, however, some elements are missing probably due to oxidation. In our research group, the mechanism of PGM dissolution into slags has been investigated to clarify suitable conditions for the recycling process. Solubilities of PGMs, such as Pt, Rh and Ru, into various composition of slags were measured together with their temperature dependency. By reviewing the results, dissolution mechanism of each element will be discussed in the present paper.
