According to the differences in physical and chemical properties between elements, scholars generally classify rare earth elements into light rare earth elements and heavy rare earth elements. Among them, the light rare earth elements mainly include: 镧, é•, 铈, 镨, é’•, é’·, é’, é“•. The main thing I want to introduce today is the application of centrifugal extractor in the extraction of light rare earth elements.
First, the market application of light rare earth elements:
Before we understand the extraction technology and equipment of rare earth elements, let us first understand the market application of light rare earth elements. The rare earth industry has a history of more than two centuries, and its application has become increasingly widespread. At present, the application of rare earth elements has been extensive, and can be used in many fields such as metallurgy, ceramics, chemicals, electronics, medical, and superconductivity. The scope of use is so great that it reflects its value.
Second, the extraction method of light rare earth elements:
According to statistics, the main methods for extracting rare earth elements include solvent extraction, fractional crystallization, and ion exchange. The crystallization method and the exchange method have certain limitations due to their own defects. For example, the crystallization method is only suitable for small-scale experimental research and is not suitable for industrial production. The ion exchange method is only suitable for purifying rare earths with lower concentration. liquid. Only solvent extraction can be used in many fields, suitable for experimental and industrial production. Therefore, this method is also the most widely used at present. 
Third, the application of centrifugal extractor in the extraction of light rare earth elements:
After the method is determined, the device is determined. It is described above that the extraction of light rare earth elements is more suitable by solvent extraction. The solvent extraction method is also suitable for use with a centrifugal extractor. The centrifugal extractor produced by Tianyi extraction is very suitable for use in the extraction of light rare earth elements. The experimental results show that the separation efficiency is high, the extraction ability is large, and the continuous operation performance is good. In addition, there are many advantages such as cost saving and small floor space. And this is a new type of equipment, which also plays a certain role in the future technological innovation and innovation of the company.
