Rare earth resources refer to 17 lanthanide elements in the periodic table of chemical elements, including lanthanide (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), yttrium (Yb), lutetium (Lu), as well as two elements closely related to the 15 lanthanide elements - scandium (Sc) and yttrium (Y). Elements, known as rare earth elements, also known as rare earth resources, abbreviated as rare earths. Rare earths have important applications in military, metallurgical industry, petrochemicals, glass ceramics, new materials, and other fields, and are known as the "gold" of industry. The key manufacturing areas that China will focus on developing in the future, such as high-end equipment manufacturing, new energy industry, new materials industry, and new energy vehicle industry, are closely related to rare earths. Rare earths are strategic mineral resources that China attaches great importance to, so efficient mining of rare earth resources has important strategic significance.
In industrial mass production of mixed rare earth metals, the molten salt electrolysis method is generally used. This method involves heating and melting rare earth compounds such as rare earth chlorides, and then electrolysis to precipitate rare earth metals on the cathode. Molten salt electrolysis is the main method for producing mixed rare earth metals and single light rare earth metals such as lanthanum, cerium, praseodymium, and neodymium. Samarium, europium, ytterbium, and thulium are not suitable for electrolytic preparation due to their high vapor pressure, and are instead prepared by reduction distillation.
In the process of producing rare earths by molten salt electrolysis, stable direct current needs to be supplied. The electrolytic rare earth power supply produced by Hebei Tongke adopts advanced PWM pulse width modulation technology and uses IGBT as the power switch device. It has small size, light weight, full functionality, stable and reliable performance, high power factor, low ripple, less pollution to the power grid, strict and complete production process, and can save 15% -30% energy compared to thyristor rectifier power supply. This series of products adopts advanced DSP control system and has automatic current/voltage stabilization function, which does not change with voltage and has high reliability; Equipped with PLC interface and RS485 interface extension function, it is convenient to achieve automation control. The performance of this electrolytic rare earth power supply fully meets the various parameter requirements of electrolytic rare earth, and can provide stable DC power supply for the electrolytic rare earth process.
