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.
