FOERFARANDE FOER SEPARERING OCH AOTERVINNING AV KOBOLT OCH NICKEL FRAON DERAS VATTENLOESNINGAR

摘要

Process for treating aqueous acidic solutions of cobalt and nickel values using certain fluorinated beta -diketones wherein the cobalt values are preferentially stripped 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.
