How Is Platinum Extracted? Reference

Apr 13, 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.

How is platinum extracted from its ore

Sep 19, 2014· An ore is a naturally occurring mineral from which a pure metal can be extracted. For Platinum, the two- chief minerals are sperrylite or platinum arsenide (PtAs2) and co-operate or platinum sulfide (Pts). Extracting Platinum from these ores is arguably one of the most capital and labour intensive operations in the world.
