What Are Platinum Group Metals (PGMs)? - ThoughtCo
10-12-2018· The platinum group metals (PGMs) are six transitional metal elements that are chemically, physically, and anatomically similar. The PGMs are the densest known metal elements. Exceptionally rare, the six metals naturally occur in the same ore bodies. They are highly durable and, due to their high value, often recycled, giving them long life cycles.RECYCLING OF PLATINUM GROUP METALS FROM AUTOMOTIVE,,Platinum 2012 695 R. Rumpold, J.

How Is Platinum Extracted? - Reference
13-04-2020· 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. This process is necessary,,,,,
