| Outline of Final Research Achievements |
In recent years, there have been significant changes in the supply and price of rare earth metals and compounds. Considering the serious shortage in the supply of rare earth minerals and the environmental problems related to the mining and smelting of these ores, it is essential to develop a new process for production and recycling rare earth metals and their compounds. In this study, the current status of rare earth metals and compounds, especially scandium(Sc), was reviewed. Further, various types of production and recycling processes are investigated. Some fundamental experimental work on reduction and deoxidation of reactive metals was also carried out at the Okabe laboratory. The advantages and disadvantages of the new processes are evaluated, and the possibility of establishing new processes in the future is discussed from a multilateral perspective.
