阅读说明：本技术 Li回收方法和现场生产用于Li回收方法的化学品 (Li recovery process and on-site production of chemicals for Li recovery process ) 是由 S·达拉 B·扎希利 于 2019-12-19 设计创作，主要内容包括：本公开介绍了用于使Li回收方法中所需的酸、碱和盐试剂再循环的方法。实施包含氧去极化阴极的膜电解池以在现场产生所需的化学品。该系统可以利用一部分盐沼盐水或其他含锂的盐水或固体废物产生盐酸或硫酸、氢氧化钠和碳酸盐。同时产生酸和碱使得可以在从盐水和矿物岩石中回收Li的常规方法中利用这两种化学物质。脱盐的水也可用于回收方法中的洗涤步骤或返回到蒸发池塘中。该方法还可用于将锂盐直接转化为高价值的LiOH产品。该方法不产生任何固体流出物,这使其易于用于现有的工业Li回收设备。(The present disclosure introduces a process for recycling acid, base, and salt reagents required in a Li recovery process. Membrane electrolytic cells comprising oxygen depolarized cathodes are implemented to produce the desired chemicals in situ. The system can utilize a portion of the saltwater or other lithium-containing brine or solid waste to produce hydrochloric or sulfuric acid, sodium hydroxide, and carbonate. The simultaneous production of acid and base makes it possible to utilize both chemicals in conventional processes for recovering Li from brine and mineral rocks. The desalinated water may also be used in a washing step in a recovery process or returned to the evaporation pond. The process can also be used to convert lithium salts directly into high value LiOH products. The process does not produce any solid effluent, which makes it easy to use in existing industrial Li recovery plants.)
