摘要

摘要:
锂是新能源产业发展不可或缺的关键矿产原料。2018年锂电池行业的锂消费量占比56%，超过其它行业锂消费量的总和。尽管卤水锂资源总量占据优势，并且卤水提锂成本低于矿石提锂，但2018年以来矿石提锂产量超过卤水提锂产量，未来矿石提锂产量占比仍将进一步提高。基于矿石提锂的举足轻重地位，对锂辉石、锂云母、铁锂云母、透锂长石和磷锂铝石等岩石矿物提锂技术进行综述，总结分析硫酸法、石灰烧结法、硫酸盐法、氯化焙烧法和压煮法在矿石提锂方面的研究进展，指出未来矿石提锂技术趋势是降能耗、降成本。

Abstract:
Lithium is an indispensable critical mineral raw material for the development of new energy industries. With the rapid development of new energy vehicles and energy storage industries, lithium consumed in rechargeable lithium batteries is increasing year by year. In 2018, the lithium consumption of the lithium battery industry accounted for 56%, exceeding the total lithium consumption of other industries. However, the output of lithium extraction from ore has exceeded the output of lithium extraction from brine since 2018. The proportion of lithium extraction from ore will continue to increase in the future. Because of the pivotal status of lithium extraction from ore, this paper summarizes the lithium extraction technologies from rock minerals such as spodumene, lepidolite, zinnwaldite, petalite and amblygonite, and discusses the research progress of lithium extraction technologies such as sulfuric acid method, lime sintering method, sulfate method, chlorination roasting method and pressure cooking method. It is pointed out that the future trend of lithium extraction from ore is to reduce energy consumption and cost.
