Rhodium, as a precious platinum group metal, has irreplaceable applications in many high-tech fields because of its rarity and unique chemical and physical properties. Therefore, understanding the price of rhodium and its refining method is of great significance for industrial production and scientific research.
The price per kilogram of rhodium
The price of rhodium is affected by multiple factors such as global market supply and demand, mineral resource exploitation cost and macroeconomic environment, and the price fluctuates greatly. Because my knowledge is updated to April 2023, I cannot provide the latest rhodium price, but according to the previous data, the price of rhodium has fluctuated between hundreds of thousands to millions of yuan per kilogram. Interested readers can obtain the latest price information through the professional metal market information platform or the precious metals trading market.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48295.html

Method of refining rhodium
The rhodium refining process is complex and delicate, mainly through the following steps:文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48295.html
1. Ore processing
First, rhodium-containing substances are extracted from ores containing platinum group metals. This process usually involves the crushing of the ore, grinding it and separating out the parts containing precious metals such as rhodium through a flotation process.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48295.html
2. Smelting
The processed ore is then melted, where high temperatures separate the rhodium-rich material from the rest. In this step, rhodium is usually extracted along with other platinum group metals.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48295.html
3. Chemical extraction
The product obtained after smelting needs to be further separated from pure rhodium by a chemical refining process. This step includes methods such as solvent extraction, in which the rhodium is separated from other metals by a chemical reaction, and electrolysis, in which the rhodium is deposited on the cathode by an electric current in an electrolytic cell to obtain a higher purity rhodium.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48295.html

Step 4: Purification
Finally, rhodium is further purified by a series of chemical and physical methods to remove the residual impurities. The purification process may include repeated dissolution and precipitation steps to ensure that the obtained rhodium is pure enough for industrial applications or scientific research.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48295.html

The rhodium refining process is a highly specialized job that requires complex chemical treatment and sophisticated equipment support. Despite the extremely high price per kilogram of rhodium, its applications in catalysts, electronic devices, jewelry manufacturing and other fields have kept the demand for rhodium growing. With the improvement of refining technology and the strengthening of resource recycling, the supply of rhodium is expected to be more stable, but its rarity and application value will remain unchanged.文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48295.html 文章源自平泽贵金属回收公司 www.51gjs.comPINGZE Precious Metals Recycling-https://en.51gjs.com/48295.html
