Abstract:
For the recovery of rare metals from urban mine, pyrochemical approaches such as fluoride or chloride processes have potentials for waste reduction and effective recycling. In this paper, advantages of fluoride and chloride processes are introduced based on the experimental study. Separation of refractory metals such as tantalum and niobium are also examined by fluorination or chlorination methods. Finally, the applicability of halide processes to rare metal recycling is discussed.
