| 英文摘要 | With the rapid development of cutting-edge industries such as electronics and materials, niobium has been regarded as a crucial strategic metal resource due to its unique physicochemical properties. The demand for niobium is increasing year by year, and the metallurgical extraction technologies of niobium have also received more and more attention. China's Bayan Obo region is rich in niobium resource, but it has not been effectively exploited and utilized yet as a result of the low-grade niobium, complicated ore phases, and difficulty in beneficiation and separation. Developing suitable niobium extraction technologies from low-grade niobium resources in China has important research value and strategic significance. In this review, the research status of main niobium extraction technologies from low-grade niobium resources including pyrometallurgical reduction, acid decomposition, alkali decomposition, chlorination, and combined pyrometallurgy-hydrometallurgy technology is summarized. The advantages and characteristics of various technical processes above are concluded. The effect of low-grade niobium on niobium extraction is discussed. Besides, the sub-melting salt method and the combined roasting-acid leaching method developed in recent years are also used to extract niobium from low-grade niobium resources. These two methods demonstrate great extraction effect and application value, and expansive prospects. The former has great potential owing to its high decomposition rate and light environmental burden. Existing studies have shown that the latter is able to decompose low-grade niobium ores more efficiently, and the leaching rate of niobium reaches 98%. Finally, the problems existing in the current technologies of niobium extraction from low-grade niobium resources and future research and development directions are summarized and previewed. 漏 2021, Editorial Board of CIESC Journal.
