Description

Technical Field

[0001] The utility model relates to the technical field of manganese sulfate solution treatment, in particular to a device for removing cobalt and nickel in manganese sulfate solution. Background Technique

[0002] Metallic manganese is an important industrial raw material. The electrolysis method is one of the methods to obtain metallic manganese. Its basic steps are as follows: First, manganese ore is used as the raw material, which is crushed and then added with sulfuric acid to make a manganese-containing leaching solution, namely manganese sulfate solution. Then, the manganese sulfate solution is subjected to impurity removal treatment and used as the electrolyte for electrolysis to obtain metallic manganese. In the production of electrolytic manganese, the cobalt and nickel contained in the raw material manganese ore have a great influence on the production process of electrolytic manganese, and they are harmful elements that must be removed during the production process of electrolytic manganese. At present, the electrolytic manganese industry mostly uses the flocculation precipitation method to remove cobalt and nickel impurities, that is, a flocculant is added to the manganese sulfate solution to make the impurities in the solution flocculate and precipitate. However, this method is only suitable for the preliminary purification of solutions containing a large amount of impurity ions, and the purification effect is not complete, and it cannot separate and recover cobalt and nickel well.

[0003] As disclosed in a device for separating cobalt and nickel in manganese sulfate solution with the authorization announcement number CN217324229U, it includes a kettle body and a rotating rod. The rotating rod is vertically rotatably installed in the middle of the kettle body, and a stirring rod is fixed on the outer circle of the rotating rod. There are multiple stirring rods. A vertical rod is vertically fixed inside the right side of the kettle body, and a sleeve ring is slidably sleeved on the outer circle of the vertical rod, and an airbag is fixed on the outer circle below the sleeve ring. In the utility model, a vertical rod is vertically arranged inside the kettle body, a sleeve ring that can slide up and down is sleeved on its outer circle, and an airbag is fixed below it, so that two temperature sensors are installed above and below the installation rod. Since the airbag can always make the sleeve ring float on the surface of the solution, the two temperature sensors can always be located inside the kettle body above the solution and inside the solution, and can respectively monitor the temperature of the solution and inside the kettle body, and can obtain a more accurate monitoring effect on the temperature of the solution and inside the kettle body. However, this utility model lacks a heating mechanism and a reactant adding mechanism, which is not convenient for the reactant addition ratio and temperature control of the device. Therefore, we propose a device for removing cobalt and nickel in manganese sulfate solution, which solves the problems of reactant addition and temperature control of the device and improves the use convenience and processing effect of the device.
