Palladium Refining Tutorial-Part 1
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 ...
