SEPARATION AND RECOVERY OF COBALT AND NICKEL FROM AQUEOUS SOLUTIONS THEREOF

摘要

SEPARATION AND RECOVERY OF COBALT AND NICKEL FROM AQUEOUS SOLUTIONS THEREOF Process for treating aqueous acidic solutions of cobalt and nickel values using certain fluorinated .beta.-diketones wherein the cobalt values are preferentially s-tripped from the loaded organic phase. Variations include preferential extraction of cobalt values, recovery of nickel from the raffinate and a second stripping step to recover nickel from the loaded organic.
