    Abstract:

    The expansion of the electric vehicle market is expected to lead to the rapid growth of the lithium-ion battery market [1]. Accordingly, the amount of scrap is also expected to increase, so various attempts are being made to recover valuable metals (nickel, cobalt, etc.) from the scrap [2]. The methods include the pyrometallurgical process, hydrometallurgical process, and direct recycling process, and comparison of each process is also being discussed [3]. However, process development, such as mutual complement of the process, continues. We have investigated the continuous pilot testing of a solvent extraction process to recover nickel and cobalt from secondary battery scrap for the production of high purity nickel sulfate and cobalt sulfate for secondary batteries.
    The solvent extraction process is composed of three different solvent extraction processes, and each solvent extraction process is generally composed of extraction, scrubbing, and stripping step. The continuous process was operated for about 200 hours, and the steady state of the process was confirmed through pH observation and quantitative analysis of components, and stability of the process was secured through continuous operation.
