稀土资源提取技术进展及趋势

Progress and Trend of Rare Earth Resources Extraction Technology

稀土是重要的战略性资源,是全球高新技术产业发展的关键元素,在全球工业经济发展中的作用日趋重要,稀土资源的合理开发对全球稀土资源供给至关重要。综述了混合型稀土矿、氟碳铈矿矿石、离子吸附型稀土矿以及深海沉积物中稀土的分离提取工艺现状及进展,提出了稀土资源提取技术发展趋势,认为开发高效、低成本、实用的绿色提取分离工艺技术是稀土资源提取分离技术的趋势。

Rare earths are an important strategic resources,which are the key elements of the development of high-tech industry in the world,and its role in the development of global industrial economy is becoming increasingly important.In this paper,the status and progress of separation and extraction technology of mixed rare earth ore,bastnaesite ore,ion-adsorption type rare earth ore and deep sea rare earth are reviewed.The development trend of rare earth resource extraction technology is introduced.The development of efficient,low-cost and practical green extraction and separation technology is still the trend of rare earth resource extraction and separation technology.
