Description

A method for manufacturing a permanent cathode Technical Field

[0001] A method for manufacturing a permanent cathode, relating to a method for manufacturing a permanent cathode. Background Technology

[0002] In the hydrometallurgical process of non-ferrous metals, permanent cathode electrolysis is a common method for producing metal products. For example, the permanent cathode method for producing cathode copper products has been widely used. However, it has not been industrially applied in the production processes of some metals, such as the electrolytic production of metallic nickel. This is mainly because when nickel ions are deposited on the permanent cathode, the deposited metallic nickel is relatively easy to detach when the permanent cathode is made of titanium, while it is difficult to peel off from a stainless steel permanent cathode. Currently, no suitable metal material and processing method have been found for the permanent cathode that can meet the requirements of electrolytic production of such metals. Technical issues

[0003] Permanent cathodes produced using conventional materials and manufacturing methods cannot be used for the large-scale production of some metals. Technical solutions

[0004] A method for manufacturing a permanent cathode, characterized in that: a certain number and a certain area of ​​stainless steel material are inlaid on the surface of a titanium permanent cathode plate, and a strong adhesive force is formed between the precipitated metal and the stainless steel, so that the metal adheres to the titanium permanent cathode and does not fall off. After the electrolysis production is completed, the metal product is easily peeled off from the cathode plate. The materials constituting the permanent cathode can be a combination of various metal materials such as titanium, stainless steel, and aluminum alloy. The permanent cathode can be an integral permanent cathode with uneven cathode surface properties, which is formed by combining various metal materials through mechanical processing, or it can be a permanent cathode with uniform cathode surface properties, which is formed by melting various metal materials together to form an alloy with uniform properties and then processed into a permanent cathode with uniform cathode surface properties. Beneficial effects

[0005] The processed permanent cathodes are used in the electrolytic production of metals such as nickel and cobalt. They are highly operable and can effectively improve industrial production efficiency and reduce production costs. Attached Figure Description

[0006] Figure 1 is a schematic diagram of a permanent cathode manufactured using a permanent cathode manufacturing method. In the figure, 1 represents a permanent cathode plate; 2 represents a conductive rod on the cathode plate; and 3 represents other metal materials fixed to the cathode plate. The best embodiment of the present invention

[0007] The best implementation method is to use titanium and stainless steel to process the body of the permanent cathode plate, so that the processed permanent cathode can be used in the production of nickel electrolysis, which can effectively improve the production efficiency of nickel electrolysis industry and reduce production costs. Embodiments of the present invention

[0008] Stainless steel cylinders are fixed to a titanium permanent cathode plate. A 3mm diameter stainless steel cylinder is inserted through the surface of a titanium permanent cathode plate measuring 800mm long, 650mm wide, and 3mm thick, and fixed to the plate. One cylinder is fixed every 50mm in length and 50mm in width. After fixing, the stainless steel is ground until it is as smooth as the surface of the permanent cathode plate. The edges of the permanent cathode are insulated, and the permanent cathode plate undergoes necessary treatment. The treated permanent cathode is used for nickel electrolysis production, electrolyzing at a current density of 230 amperes per square meter for 240 hours. The cathode plate is then removed, and the cathode is struck with a steel pipe, causing the nickel product plate to detach from the permanent cathode plate, completing the process of producing metallic nickel from a permanent cathode. Industrial applicability

[0009] The processed permanent cathodes are used in the electrolytic production of metals such as nickel and cobalt. They are highly operable and can effectively improve industrial production efficiency and reduce production costs. Sequence List Free Content
