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 .
The ion exchange resin (IER) method is very excellent and efficient for acetone purification. Acetone will pass cation exchange resins first and then the anion exchange resins, more than 95% methylamine will be removed.
On November 23, 2020，Forbes announced Asia’s Best Under A Billion 2019 list. Sunresin was honored to be selected. The promulgation ceremony originally scheduled to be held in Bangkok, Thailand, was carried out online due to continuous spreading pandemic.
Sunresin, anion exchange resin suppliers, gives a plan for ion exchange resin pretreatment. Let's take a look at it.
