摘要
介绍了全球锂资源的分布情况及主要存在形式,从硫酸法、硫酸盐法、氯化焙烧法、纯碱压煮法等方面综述了近年来国内外从固体含锂矿石提Li的研究现状,还从沉淀法、萃取法、吸附法等方面综述了盐湖卤水提Li的技术现状,分析讨论了各种方法的机理及优缺点并提出了改进方向,最后对固体锂矿和盐湖卤水提Li技术的发展趋势及方向进行了分析展望。
The distribution and main existent forms of lithium resources in the world are introduced.The current research status of lithium extraction from solid lithium-containing ore at home and abroad in recent years is reviewed from the aspects of sulfuric acid method,sulfate method,chlorination roasting method and sodium carbonate autoclave method.The current status of lithium extraction from salt lake brine is summarized from the aspects of precipitation method,extraction method and adsorption method.The mechanism,advantages and disadvantages of various methods are analyzed,and the direction of improvement is proposed.Finally,the development trend and direction of the technology of lithium extraction from solid lithium ore and salt lake brine are analyzed and prospected.
