Nickel, a silver-white, hard, ductile and ferromagnetic metal element that is highly polished and resistant to corrosion. Nickel is a pro-iron element, so nickel-based minerals are mostly laterite nickel ore.
Nickel is often used for electroplating because of its good corrosion resistance. In recent years, nickel sulfate has been used as a ternary positive electrode material and has received much attention.
Nickel demand is increasing year by year, China will become the world's largest nickel consumer, but China's nickel mines are mostly low-grade mines, which are difficult to mine and costly.
The traditional method of Ni recovery is by extraction. Pretreatment by precipitating Fe3+ is needed before extraction. During the precipitation, around 10% Nickel would enter into the residues and are very hard to recover. On the other hand Saponification of the extractant will consume NaoH.
Sunresin has developed Special Nickel-selective chelating resin, which is designed for extracting nickel from laterite-nickel resource.
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. Sunresin has successfully established the first high-purity nickel production line in China .
Sunresin has established its Remote Solution Operation and Monitoring Center (RESOM) recently, in an effort not only to offset the impact of the travel restrictions due to the pandemic, but also to develop this innovative initiative to a higher and permanent level in a sustainable manner.
Sunresin has set up special topics and established a special research team based on customers’ needs to conduct research and analysis on the element composition and existing technology of tungsten leaching solution, and successfully developed sepcial resin Seplite® LSC680 for tungsten and molybdenum separation as well as the matching process.
Sunresin developed Seplite LXA8101 a macroporous adsorbent based on a polymerized Styrene DVB matrix. The adsorbent has been so designed to offer a high capacity and can be used in the purification of many different herbal extracts.
