DZ272 extractant used evaluation from Jiangxi Zili

Reply on the Use of DZ272 Extractant
Our branch uses DZ272 extractant produced by Zhengzhou Deyuan Fine Chemicals Co., Ltd. to extract and separate nickel, cobalt, and magnesium from nickel sulfate solution. The magnesium content in the original solution is between 3.0-6.0g/L, and the cobalt content is between 1.0-2.0g/L. The average magnesium content in the residual nickel sulfate solution is 0.001 g/L, and the average cobalt content is 0.003 g/L. It has been in use for over a year, with stable quality and very satisfactory extraction results.
