Quaternary ammonium salt extraction agent and tertiary amine extraction separation of nickel and cobalt chemical formula has many similarities, but stronger than tertiary amine and quaternary ammonium salt extraction turntable extraction tower using quaternary ammonium salt extraction agent, separation of cobalt nickel process under the PH5 value can still be effectively extracting in ionic form. Turntable extraction tower can also use the quaternary ammonium salt extractant in removing impurity from cobalt nickel solution, such as extraction of iron, copper, zinc, etc. In addition, quaternary ammonium salt was proposed for purification of nickel electrolyte. Before using the separation of nickel and cobalt, material liquid with precipitation to remove most of the iron, in order to improve the solution of cobalt concentration, rotary extractive tower need before separation of nickel and cobalt in the promote increase extraction rate.
