How Is Platinum Extracted? - Reference

13/04/2020  It is incredibly difficult to find in large pure quantities, so it needs to be extracted from the ore in a very specific way. Platinum ore can be obtained through controlled explosions or by advanced mining techniques. Once it has been mined, the platinum is extracted from the ore in the same way. The platinum ore

How is platinum extracted from its ore - SlideShare

19/09/2014  1. How is platinum extracted from its Ore? 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. On average, it takes up to six months and up to 12 tonnes of ore

Potential Processing Routes for Recovery of Platinum

06/11/2017  The beneficiation of platinum group metals (PGMs) from pristine (unweathered) sulfide ores has conventionally been conducted through froth flotation, which typically achieves platinum recoveries of over 85%. The achieved successes of PGM concentration by flotation from the pristine sulfide ores are largely due to the occurrence of PGMs in close association with base metal sulfide
