Product Details
uses HS-272 extraction to separate nickel and cobalt. Through 5-stage countercurrent extraction, the separation coefficient βCo/Ni of nickel and cobalt reaches 9.5 × 103
. HS-272 is completely suitable for separating nickel and cobalt from nickel and cobalt liquid with high nickel underestimation. It is an excellent extractant for separating nickel and cobalt. Advantages of
HS-272:
1. Cobalt extraction is preferred over calcium, entrainment of calcium in the cobalt cake during cobalt precipitation can be avoided, resulting in impure cobalt.
2, suitable for high nickel low cobalt system, even if the nickel cobalt ratio reaches more than 10, there is still a high nickel cobalt separation coefficient.
3, not easily soluble in
