I’m looking for some information on the extraction and separation of nickel and cobalt
Thread Content
The extractants currently used for the separation of nickel and cobalt
P204 for impurity removal, p507, or LIX84-IT extraction can all be used; it depends on the specific conditions of your feed solution.
On pages p204 and p507, it is mentioned that a company in Jiangsu uses these two types of extractants, and the results are quite good.
We also use these two types of extractants; it’s just that sometimes control is not perfect, resulting in a higher nickel content in the cobalt
P204，P507.. Sometimes methods such as precipitation are used to remove impurities. .
The key to controlling the extraction technology for cobalt-nickel separation is experienced technicians; experience in color control is very important
P204, P507, PBT; sometimes a mixed extractant can achieve better separation results
Among the extractants commonly used for cobalt-nickel separation, Cyanex272 is the best in terms of separation coefficient, followed by P507, and then P204. Commonly used in chloride salt systems are N235, TBP, etc.
P204 and P507 are generally used; Cyanex272 is too expensive, so few manufacturers use it``
Hehe, those who can afford to use CYANEX272 for separation will definitely get a much bigger year-end bonus this time! The separation of nickel from cobalt in the raffinate can be achieved using resin separation; it is said that Jinchuan Group is currently using metal separation equipment from Shanghai Xien Company, and the results are quite good. There’s a lot that FYMXQQ knows on the forum!
