Product performance and application:
The extraction methods of manganese metal mainly include thermal method (fire method) and electrolytic method (wet method). Electrolytic metal manganese), its purity can reach more than 99.7-99.9%. Now, electrolytic production has become the main way of manganese metal production. The key to the product quality and output of electrolytic manganese is the performance of the anode plate.
At present, the anode plates for electrolytic manganese produced by our company mainly include: Pb-Sn-Sb-Ag alloy, Pb-Sn-Sb-Ag-Bi alloy, etc. It has the characteristics of flat surface, dense board body, good electrical conductivity, high electric efficiency, good corrosion resistance, easy maintenance, long service life, etc., and is accepted and used by the majority of users.
Product technical indicators:
(1) The electrolytic manganese anode plate developed and produced by our company for many years has excellent mechanical properties, good electrical conductivity and catalytic activity, and strong corrosion resistance. The plate is not easy to break and deform during production and use, which effectively prolongs the service life of the entire anode plate, and the service life can reach more than 18-24 months, which greatly reduces the production cost for the enterprise;
(2) In order to improve the service life of the anode plate, our company has increased the surface area of the anode plate. Compared with the traditional anode plate, the specific surface area of the anode plate after increasing the surface area has doubled. At the same current density Under certain conditions, the current density on the surface of the anode plate is only half of that of the traditional anode plate, which can significantly reduce the electrochemical corrosion of the anode plate and the dissolution of the anode plate, thereby improving the service life of the anode plate.

The advantage of the Fence-type anode for Manganese EW
- The Fence-type anode plate does not need to add any auxiliary equipment in the use process, and will not deform in the use process.
- At the same time, it improves the fluidity of electrolyte, enhances the transfer speed of manganese ion, and finally improves the current efficiency of manganese electrowinning.
- Oxygen on the surface of barrier anode is easy to form small bubbles, which takes up little space to attach to the anode, has little shielding effect on the electric field, and increases the conductive area of the anode, resulting in high current efficiency in the process of manganese electrowinning
- At the same time, when the bubble rises to the liquid level, it will bring out less acid mist
