摘　　要：为解决我国锂资源相对短缺的问题,减轻进口依赖度,保障国家资源安全,需要加快黏土型锂矿资源的开发。综述了全球黏土锂资源现状,介绍了目前全球黏土型锂矿资源的分布与储量、黏土型锂矿资源的特点,汇总了国内外黏土型锂矿提取技术研究进展,分析了黏土型锂矿提取技术未来的发展趋势。我国黏土型锂矿资源丰富,分布范围广泛,开发黏土型锂矿有助于缓解国内锂资源供给,未来需加强对黏土矿物勘探和选冶技术深入研究,加快黏土型锂矿的开发,以助于做好锂资源战略储备,助力新能源产业蓬勃发展。In order to address the relative shortage of lithium resources in China,reduce reliance on imports,and ensure national resource security,the acceleration of the development of clay−type lithium mineral resources is imperative.This study presents a comprehensive review of the global status of clay lithium resources,which includes a detailed account of the current distribution and reserves of clay−type lithium minerals,as well as an examination of their inherent characteristics.Moreover,the developments in the technologies used to extract clay−type lithium minerals,both domestically and internationally,have been collated,and an analysis of the future development trends of these technologies has been conducted.It is evident that China has a considerable abundance of clay−type lithium minerals,which are geographically dispersed.The development of these resources would considerably mitigate the domestic lithium supply challenges.It is recommended that future research should concentrate on the improvement of exploration and extraction technologies that are specific to clay minerals.This would facilitate the accelerated development of clay−type lithium resources,reinforce strategic lithium reserves and support the sustainable growth of the new energy sector.
