Although more than 60 countries have discovered and mining platinum ore, their reserves are highly concentrated in South Africa and former Soviet Union. The total reserves of the two account for 98%of the world's total reserves. The annual output of the world's platinum is only 85 tons, which is far less than gold. In addition, the platinum melting point is higher. Polying platinum is more difficult than gold and consumes high energy. Therefore, its price is more expensive than gold. Platinum ore can be refined after 5 months. In the classification of minerals, the platinum elements are natural platinum, including the natural element minerals of 铱, 铑, 钯, and platinum.
