As a precious metal, platinum is not only widely used in jewelry manufacturing, but also plays an irreplaceable role in the industrial field. However, with the reduction of platinum resources, platinum recovery and purification technologies have become particularly important. This article will analyze the platinum recovery process and platinum purification methods in detail, taking you into this mysterious and interesting field.
- Platinum recycling process
The first step in platinum recovery is collection. Recyclers collect platinum from a variety of sources, including old jewelry, cutlery, industrial waste, automotive catalysts, and more. After the collection is complete, these items must be fully inspected and identified to ensure their authenticity and platinum content.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48746.html
The collected platinum is then taken to a professional recycler to be weighed. This step is to determine the weight of the platinum and provide a reference for subsequent evaluation and value calculation. The recycler will assess the value of the platinum based on its weight, purity and the prevailing market price, and make a reasonable offer.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48746.html
If both sides agree on a price, the recycler will buy the platinum. During the acquisition process, the recyclers conduct thorough documentation and management to ensure that every gram of platinum is properly disposed of.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48746.html
Second, platinum purification method文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48746.html
Pure platinum is a complex and detailed process. The main purification methods commonly used are smelting, chemical and electrolysis.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48746.html
The first is the smelting method. The smelting method has the method of separating platinum from other impurities by high temperature. The platinum raw material is put into the furnace and heated to high temperature to melt the platinum, and other impurities are separated due to different dissolution points. This method is simple and easy to use, but the purity is relatively low.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48746.html
The second method is chemical. Chemical process is a method of separating platinum from other metallic elements through chemical changes. For example, aqua regia solution is one of them. Platinum is placed in aqua regia, dissolved through chemical changes, and then extracted from the aqueous solution through filtration, precipitation and other steps. This method can obtain a higher purity of platinum, but the operation process is more complicated.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48746.html
Finally, there is electrolysis. Electrolysis is a method of separating platinum from the electrolyte through an electrolytic process. Platinum raw material is added to the electrolyte, and then electrolysis is carried out. The platinum will precipitate on the electrode, thus achieving the purpose of purification. This method can obtain high purity platinum, but the equipment cost is high.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48746.html
During the purification process, some details should also be paid attention to. For example, the temperature, pressure and amount of chemicals are strictly controlled to ensure the stability and efficiency of the purification process. At the same time, strict quality testing is carried out on pure platinum to ensure that it meets the specified standards and requirements.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48746.html
- Unique insights
With the continuous development of science and technology, platinum recovery and purification technology is also constantly innovative and optimized. In the future, we can look forward to the emergence of more efficient and environmentally friendly platinum recovery and purification methods. At the same time, with the improvement of people's environmental awareness, platinum recycling will also become a trend to contribute to sustainable development.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48746.html
In short, platinum recovery and purification is an important job. It not only helps to save energy and protect the environment, but also provides a stable supply of platinum for jewelry manufacturing, industrial production and other fields. By understanding the processes and methods of platinum recovery and purification, we can better understand this precious metal and contribute to its future application and development.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48746.html 文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48746.html
