Separation technology of rare earth elements(REEs),as the critical step in the separation process,had long been fraught with technical difficulty.A research project conducted by Baotou Shibo Rare Earth Extraction&Equipment Co.Ltd.,Baotou REE Research Institute,and Baotou Steel&REE Group Hi-Tech Co.Ltd(Inner Mongolia),has successfully solved the problem using a centrifugal extractor and advanced techniques to achieve a key breakthrough.The key device of the whole production line contains CTL-500FB centrifugal extractors and digital flow system equipment.Employment of an automatic controlling system and its fully functional operation system,along with various supportive facilities,fulfils the separation processes for various rare earth materials.Compared with conventional box-type separation technology,this new approach significantly improves the stirring intensity,thus improving production Separation technology of rare earth elements (REEs), as the critical step in the separation process, had long been fraught with technical difficulty.
