What’ Copper Metal AnodeA copper metal anode is a node that permits current to stream into an electrical appliance. It is usually, but not always, the positive pole of an electrochemical cell where anions (negatively charged ions) are concentrated. There are many types of the anode, such as graphite anode and aluminum anode. Copper anodes are different from these because they are specialized in copper refining, a process known as copper smelting.
Raw Materials for Copper Metal AnodesCopper anode material comes from two places; Copper is a refined or used material. Refined copper occurs as cathode copper because copper is refined by electrolysis (electroplating from solution). In this process, the foam copper (about 95% copper) is anodized; the high purity copper is slowly plated on the cathode, and impurities are deposited as sludge at the bottom of the plating bath. Pollutants in the sludge contain iron, sulfur, tellurium, selenium, gold, silver, zinc, arsenic, and other impurities. Scrap copper is produced worldwide, from utility lines, telephone lines, transformers, water pipes, bus lines, and other sources. Such materials are generally grouped and classified by that waste dealer. The disadvantage of scrap metal is that it can be contaminated. All previously mentioned sources contain steel, tin, silver, and lead. The metals may also be mixed during sorting, and copper alloys may be mistaken for pure copper.
The grain structure of Copper Metal anodeThe grain structure is an essential characteristic of the copper anode. This structure is entirely determined by manufacturing the anode, and we will now discuss this issue. Casting copper anode is the simplest and lowest cost method. However, the cast copper anode does not exhibit the fine, uniform grain structure required for excellent plating. Higher casting speed will increase yield, reduce costs, and result in larger grain sizes and, therefore, poorer grain structure.
Copper Metal Anode Productionit needs to be treated after casting. It typically includes hot rolling, hot extrusion, or hot forging To produce the copper anode with a fine grain structure. When copper is formed at high temperature and high pressure, the grain structure is modified to become refined and uniform. In extra to the anode, copper for different processes also demands a good grain network (wire, bus bar, copper foil, and sheet). Production of anode copper Copper anodes are assembled by grinding a copper ore named chalcopyrite (CuFeS2) and mixing it with water, pine oil, and pentyl furoate, a salt used to keep the mixture out of water. Compressed air is passed through the variety for further purification after the mixture is made. Next, the chalcopyrite mixture was combined with limestone and sand and heated to about 2,300°F (1,110°C) in an oxygen furnace. When the blend is warmed, oxygen in the furnace reacts with iron in the chalcopyrite to make iron oxide (II). Copper still exists in the form of copper sulfide, is an excellent electrical conductor. Sulfur dioxide is also produced as a by-product in this process.
