| Abstract (English): |
Tantalum and niobium are crucial strategic metals. Amidst the escalating demand for advanced materials in high-end manufacturing industry and the profound implementation of the green development concept, the purification and refinement of products as well as the cleanliness and circularity of processes have emerged as pivotal transformation goals for the hydrometallurgy of tantalum and niobium. In this paper, an overview of the characteristics and current utilization status of primary and secondary tantalum and niobium resources in China was provided. The latest advancements in green decomposition technologies for tantalum and niobium raw materials, separation and purification techniques for tantalum and niobium solutions, and value-added utilization technologies for metallurgical wastewater were systematically introduced. The advantages and disadvantages of each technology were compared and analyzed according to industrial practice, and the prospects and suggestions were put forward from the aspects of resource security, technology development direction and comprehensive pollution control, so as to provide support for the sustainable and high-quality development of tantalum and niobium metallurgical industry・ [ABSTRACT FROM AUTHOR] |
