The Process Technology of 15000 A Electrolyzer in Production of Praseodymium Neodymium

The cell is composed of a cell body, anode, and cathode, and most of them are separated by a diaphragm. The electrolyte difference can be divided into three types: aqueous solution electrolyzer, molten salt electrolyzer, and non-aqueous solution electrolyzer. When the direct current passes through the electrolyzer, the oxidation reaction occurs at the interface between anode and solution, and the reduction reaction takes place at the interface between cathode and solution to produce the required products.
 
The process technology of the 15000A electrolyzer is to put fluoride solution into the electrolyzer, apply 15000A DC, keep the furnace temperature at about 1000 ℃. Then pour rare earth praseodymium neodymium oxide into the electrolyzer, oxidize oxygen ion to the anode and discharge it as carbon dioxide. At the final step, reduce rare earth ion to the cathode and reduce it as a metal droplet from the tube below. This is the whole process of electrolysis.
 
 
At present, the vast majority of praseodymium and neodymium metal products are mainly produced in a small electrolytic cell with a capacity of 6000A. The cell and electrolysis technology we share today, from the small cell of 6000A to the large cell of 30000A, have been tested in industry, and the technology of 15000A cell has obtained the final production process.
 
Rare earth metal neodymium and praseodymium neodymium alloy products are the critical raw materials for producing magnetic materials used in the fields of small luggage buttons, mobile phone accessories, wind turbines, and aerospace at home and abroad. Their stability directly affects the strength of the application of magnetic materials accessories.
 
This 15000A rare earth molten salt electrolysis technology has high single furnace output, long furnace life, low power consumption, and good product consistency. Therefore, it is praised highly by users at home and abroad.
