separation copper nickel
May 10, 2017· A separation factor range of 93–170 for copper over nickel was obtained in the CaCl 2 concentration range of 100–320 g/L. Considering copper extraction and its separation from nickel and cobalt, a target CaCl 2 concentration of 200 g/L is suggested to be used with the separation factor of copper over nickel and cobalt of 138 and 1020, respectively.
