摘　　要：近年来,随着新能源产业规模的持续扩充,锂电池的需要量不断上涨,世界范围内对锂的消费量呈爆发式增长,锂矿资源的开发得到了快速发展。锂辉石是提取锂的重要矿产资源之一,目前国内现有工业化锂辉石提锂工艺仍存在能耗高、污染大、废渣利用低等问题,因此开发一种新型绿色、清洁、高效提锂工艺是今后发展的重点。文章阐述了锂辉石的组成及结构,并对几种不同的提锂工艺进行了探讨。In recent years,with the continuous expansion of the scale of the new energy industry,the demand for lithium batteries continues to rise,the worldwide consumption of lithium is explosive growth,and the development of lithium mineral resources have developed rapidly.Spodumene is one of the important mineral resources for lithium extraction.At present,the existing industrial spodumene lithium extraction process in China still has problems such as high energy consumption,heavy pollution,and low utilization of waste residue.Therefore,developing a new green,clean and efficient lithium extraction process is the focus of future development.The composition and structure of spodumene are described,and several different lithium extraction processes are discussed.
