How Is Platinum Extracted? - Reference

04/08/2015· This process is necessary because platinum, even in ore, needs to be removed from other substances. Platinum is an incredibly rare metal that is mined and extracted in a variety of different ways depending on the technological sophistication of the miners attempting to extract it. It is incredibly difficult to find in large pure quantities, so it needs to be extracted from the orePlatinum Mining and Refining | Education,Refining platinum ore is a costly and laborious process. It can take from eight weeks to six months to process a batch of ore, and it can take up to 12 tons (11 tonnes) of ore to produce a single troy ounce of platinum.
