  • How Is Platinum Extracted? - Reference

    Apr 13, 2020  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 is not pure, so it is first crushed. This produces many tiny particles that can be treated.

  • How is platinum extracted from its ore - SlideShare

    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.

  • Platinum Mining and Refining Education

    Platinum is also mined as an ore . Platinum ores such as sperrylite and cooperite may be mined when they are found in quantities that make extraction economically feasible. In other situations, platinum is obtained as a by-product when ores of other metals, such as copper and nickel, are refined.
