中文摘要：

分析了中国矿山型锂矿资源分布及矿物特征,阐述了中国矿山型锂资源开发技术进展,对中国若干矿山型锂矿资源提取碳酸锂工艺路线进行了分析和比较。并指出,中国以青海盐湖为代表的盐湖卤水提锂由于较高的镁锂比,盐湖提锂一直存在技术瓶颈,目前的技术水平难以实现镁锂分离。基于中国丰富的矿山型锂矿资源状况,从矿山型锂矿提取碳酸锂仍将是中国相当长一段时期内主要的锂资源来源,中国应重视矿山型锂矿资源技术研究,加大研究开发力度,使中国矿山型锂矿资源得到有效和保护性开发。

英文摘要：

The distribution and characteristics of lithium mineral resources in China were analyzed and their technical deve- lopment progress was introduced.The process routes of extracting lithium carbonate from different lithium mineral resources in China were analyzed and compared.Because of the high ratio of Mg/Li,the extraction of lithium carbonate from the brine of salt lakes,such as Qinghai salt lake had the technological bottleneck all the time and the separation of lithium from magnesium was hard to be realized with the present techniques.Thus lithium minerals will still be the main lithium resources in China in a relatively long period, based on the richness of lithium mineral resources in China.Therefore, China should pay more attention to the technical research on lithium mineral resources and intensify the research and development work, so that the lithium mineral resources could be utilized effectively and protectively.
