Platinum refining process

Feb 28, 2018 The classical refining process is based on PGM chloride chemistry. It involves successive steps of precipitation and redissolution to purify the metals, followed by thermal reduction to metal. However, it gives a poor first time yield for refined metals and requires lengthy refining times, e.g., up to six months for rhodium [ 7 ]

    Palladium (Pd) refining can be a daunting task, similar to the other Platinum group metals (PGM's) refining process. This is mainly due to their similar (but different) physical and chemical properties. Separating Palladium from base metals and especially from sister PGM's, is rarely achieved completely in one refining cycle. Sounds kind of rough, but rest assured that this process is doable
