P204 (D2EHPA or HDEHP) metal Extractant widly be used for impurity removal for laterite-nickel ore, it has good ability for removing impurities in the process of extract nickel and cobalt, also can extract other metal as Zinc etc.
Laterite-nickel ore has complex metal ion and low content of nickel and cobalt, normally use Di-(2-ethylhexyl)phosphoric acid (D2EHPA or HDEHP) to remove impurities (most of metals), only left nickel/cobalt/magnesium ion. Use DZ272 to extract cobalt and magnesium, the balance is nickel ion.
