The first washing tank and the second washing tank are connected by a pipeline. The first automatic acid replenishing component is connected to the first washing tank for controlling the pH value of the first washing tank, and the second automatic acid replenishing component is connected to the second washing tank for controlling the pH value of the second washing tank. The utility model realizes the separation of nickel and magnesium in the organic phase during the washing process and improves the quality of the organic phase through the mutual cooperation between the first washing tank, the first automatic acid replenishing component, the second washing tank and the second automatic acid replenishing component.

[0004] Although the above technical solution solves the problem of improving the quality of the organic phase, the above technical solution involves equipment such as a first washing tank, a second washing tank, a first automatic acid replenishing component and a second automatic acid replenishing component. The automatic acid replenishing component needs to consume a certain amount of acid to adjust the pH value of the washing tank, which may have a high cost problem. Therefore, a device for separating cobalt and magnesium is needed. Utility Model Content

[0014] First, the material containing cobalt and magnesium is put into a pulverizer for pulverization, and then transported to a holding barrel through a transport pipeline for the next step of wet smelting. The cobalt-magnesium solution is then transported to a precipitation barrel through a transport pipe. The specific functional groups in the chelating resin in the transport pipe will form a complex with the cobalt ions, thereby selectively adsorbing the cobalt ions. The magnesium ions, due to their low affinity with the resin, will remain in the solution and be transported to the precipitation barrel through the transport pipe for the next step of magnesium separation. When the chelating resin is saturated with adsorption, a regeneration agent such as hydrochloric acid, sulfuric acid, etc. is used to regenerate the chelating resin to elute the adsorbed cobalt ions.

The eluted cobalt ion solution can be further treated, such as concentration, crystallization, etc., to obtain a high-purity cobalt product, which greatly reduces the cost problem in the cobalt-magnesium classification process and improves the recycling and reuse of resources.
