Ion Exchange Technique for Copper Recovery from Mines, Mining Tailings, Electroplating

Copper is the first metal discovered and used by humans and is widely used due to its good ductility, thermal conductivity and electrical conductivity.

Copper is widely used in electrical appliances, light industry, machinery manufacturing, construction industry, national defense and other industries, and its consumption is second only to aluminum. Copper is mainly obtained from the smelting of copper ore. The copper smelting process is divided into two types: fire method and wet method. High-grade ore is generally smelted by fire method, high-grade tailings and low-grade copper oxide, which are generally smelted by wet method. With the reduction of recoverable high-grade ore, wet smelting technology has gradually gained attention.

The wet copper smelting uses copper sulfate to convert the copper element in the copper ore into soluble copper sulphate, and then puts the iron into the copper sulphate solution to replace the copper. This method is called wet copper smelting. Ion exchange can efficiently recover copper from solution, which is generally suitable for tailings, or copper in wastewater.

Sunresin has developed Special copper-selective chelating resin, which is designed for extracting copper. As the first and the only A-share listed company in Chinese ion exchange and adsorption resin industry, Sunresin is one of the few integrated purification solutions providers in China.
