Palladium Refining Palladium Precious Metal

Palladium Refining Palladium, like all other precious metals, is generally not extracted on its own and in order to separate it into pure palladium bullion it has to go through a detailed refining process. Palladium refining is actually very similar to platinum refining because both metals are found bonded to others and are widely dispersed in the crust of the Earth.

Palladium Refining Palladium Scrap

Palladium is often an overlooked precious metal. People don’t always know where to find palladium scrap or whether it is worth something. Sadly, they might be missing a great deal of money because of this. When you recycle palladium scrap, you can then do palladium refining, which is the process to recover palladium from scrap metals.
