Affected by the global financial market, the price of gold will be stable for a long time and will only appreciate slightly. Because the national hard currency is gold, the main storage is gold, and platinum is scarce, so many industrial fields need to use manufacturing instruments. Only 150 tons of platinum can be mined in the world every year, of which 60 tons are used for jewelry. And the total output of gold reaches 3300 tons per year, platinum = platinum = Pt ≠ K, platinum-platinum-gold (platinum). Its main component is gold, which is not natural white, but appears white after adding other metals. Platinum is not platinum (platinum). White gold jewelry usually uses 18K or 750 to indicate the purity of gold contained in it. Only a few regions in the world produce platinum. South Africa accounts for 68%, Russia accounts for 25%, North America accounts for 5%, and the remaining 2% comes from other countries, mainly Zimbabwe. To obtain an ounce of platinum, that is, 365,438+0.65,438+0g, it takes 5-6 months to process 65,438+00 tons of ore before casting an "ounce platinum ingot" from raw materials. The same amount of gold can be extracted from 3 tons of ore in only 3-5 weeks.
