Performance Evaluation of Nickel Separation and Extraction

The higher separation factor value of nickel over chromium β Ni/Cr was obtained as 898. As a result, the nickel extractionic was found to depend on PC88A, since extraction mechanism of PC88A is slower than that of LIX63. So,bined use of LIX63 and PC88A improved the selective extraction of nickel in that process.
