Palladium Extraction by Gravimetric Precipitation

The best results from the gravimetric precipitation process are generated when we encourage large particles to be formed. These large particles when washed out in the final process will provide for purer results, rather than many small particles, due to the nature of the gravimetric process as used in refining.

How Is Platinum Extracted? | Reference.com

Because platinum is so rare, it must be extracted after being mined through a process that involves crushing it into incredibly small particles and separating these particles from one another. This is known as the flotation separation method, and produces a frothy layer of particles that can be skimmed to provide the extracted platinum.

The term "refining" is used in a narrower context. Henry Cort's original puddling process only worked when the raw material was white cast iron, rather than the gray pig iron that was the usual raw material for finery forges. For the gray pig iron to be usable, a preliminary refining process was developed to remove the silicon.
