中文摘要:
      我国已探明的钾、锂资源大多赋存于盐湖卤水矿床中,但经过多年生产地表盐湖资源消耗严重,海相地层寻找钾、锂的工作还未取得突破,深层地下卤水则可成为解决我国锂钾资源需求的后续储备。我国深层地下卤水主要分布在柴西、四川、湖北、江西等地,资源丰富,其中富含高品位的钾、锂、硼等元素,具有很好的经济利用价值,但是目前工作程度还不够,并由于开采技术、成本等问题,还未实现工业开采。文章对我国重点区块深层地下卤水的水化学特征、分布规律等进行了总结,结合已有的深层卤水资源量评价等数据,提出了下一步重点研究的建议区块,可为后续我国深层卤水钾、锂资源评价、综合提取工艺研究等提供科技支撑。
英文摘要:
      Potashfertilizeristhefertilizerofgrain.Foracountrywith1.4billionpopulation,thestablesup-plyofpotashproductsplaysaveryimportantroleinnationaleconomyandsecurity.Lithiumisthe“newen-ergy richin the 21st century”.In recent years,with the rapiddevelopment of the global new energyindus-try,lithium resources have been highly concerned by countries around the world.At present,two kinds of resources of China’s potassium,lithium depend on existence degree to be high externally,self-sufficiency is insufficient,needto raise Chian’spotassium,lithium resources guarantee degree by actively seeking ore, make full use of international resources and so on way.The proved potassium and lithium resources are mostly deposited in the salt lake brine deposit,but after years of surface salt lake production and serious consumption of surface salt lake resources,the search for potassium and lithium in the Marine stratum has not yet made abreakthrough. The deep undergroundbrine can become the follow-up reserve of our lithium potassium resource requirement. China’s deep underground brine is mainly distributed in the west of Chaixi,Sichuan,Hubei,Jiangxi and other places. It has rich resources,rich potassium,lithium,boron and other high grade elements,and has very good economic value. However,the degree of work is not enough at present,and the industrial exploitation has not been realizeddue to the problems of mining tech-nology and cost. In this paper,the keyblocks in the deep undergroundbrine water chemical characteristics and distribution regularities is summarized,based on deep brine resources evaluation of existing data,put forward the next key research proposal blocks,for subsequent deep brine potassium,lithium resources evaluation in our country,such as comprehensive extraction technology and research provide technology support.
