| Abstract Scope |
The separation of nickel and cobalt is essential to the technoeconomic success of a nickel laterite mining or lithium-ion battery recycling operation. The current standard for Ni/Co separation requires solvent extraction. This paper proposes a possibly less carbon intensive separation route via a solvent free method. An acidic leach solution from lithium ion battery scrap was used as the feed solution. Using several unit operations, a separation factor of more than 50 was attained for separate cobalt and nickel fractions. Finally, more than 95% pure nickel and 99% pure cobalt fractions were recovered from the separation. |
