In recent years, the output of platinum group metals in my country has increased year by year. In 2007, it was 3.14 tons, of which platinum was 1.688 tons, a year-on-year increase of 15.0%, palladium was 1.452 tons, a year-on-year increase of 20.2%, and the output of other platinum group metals was very small. In 2007, Jinchuan Company produced 1.6 tons of platinum group metals, accounting for about 51% of the country's total output. The supply of mineral platinum group metals in my country is far from meeting domestic consumption demand. Primary platinum ore platinum group metal content is only 0. X ～ X g/t, secondary resources of platinum group metals are materials produced after platinum group metals lose their properties during processing and use of finished products. Such resources are of various types and shapes, and their grades range from a few parts per ten thousand (even Compared with primary platinum ore, the grade is higher, the composition is simpler, the recovery process is relatively short, and the investment is less. Platinum group metal secondary resource recycling has become an important source of platinum group metals.
Therefore, the relevant system for the regeneration and recycling of secondary resources of platinum group metals in the world is being improved, and efficient and clean recycling technology has become a research hotspot文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/19175.html 文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/19175.html
