黏土型锂矿资源提锂工艺研究进展

摘要

黏土型锂矿是自然界中重要的一类锂资源,具有分布广、储量大等特点。根据成因的不同,将其分为火山岩黏土型锂矿、碳酸盐黏土型锂矿和贾达尔锂矿,分类概述了国内外对黏土型锂矿的主要提锂方法,并讨论了各方法的特点。本文指出不同黏土型锂矿中锂的赋存状态存在差异,查清锂的赋存状态是开展锂提取工作的前提。从成本、杂质分离、环保等角度,展望了具有开发利用潜力的技术方法。Clay-type lithium ore is an important lithium resource in nature,which has the characteristics of wide distribution and large reserves.It is classified into volcanic clay-type lithium ore,carbonate clay-type lithium ore and Jadar lithium ore according to the different reasons for formation.The main methods of lithium extraction from different clay-type lithium ore at home and abroad are respectively summarized,and the characteristics of each method are discussed.This article points out that there are differences in occurrence of lithium in different clay-type lithium ores,and it is a prerequisite for lithium extraction to find out the occurrence of clay-type lithium ores.From the perspectives of cost,impurity separation and environmental protection,the potential technologies for development and utilization are prospected.
