The demand for lithium increases every year and the lithium extraction and separation technology has attracted more and more interests. China is rich in lithium resource from salt lake brine， but it has not been exploited effectively due to the difficulty by high Mg / Li ratio. Thus， there are crucial research value and strategic significance to study the extraction of lithium from high Mg / Li ratio salt lake brine. In this review， the research status of popular lithium extraction technology from salt lake is summarized， including precipitation， solvent extraction， ion⁃sieve adsorption， nanofiltration and electrodialysis methods. The advantages and characteristics of the methods above are reviewed and the influence of high Mg / Li ratio on lithium separation is discussed. Moreover， the emerging solvent extraction using ionic liquid extractant and electrodialysis technology with monovalent selective permeability ion exchange membrane used to extract lithium from high Mg / Li ratio salt lake brine are introduced in detail. The two technologies exhibit great research significace and wide application prospects. The former has the potential to develop high effective lithium 收稿: 2017 年3 月9 日， 收修改稿: 2017 年5 月26 日， 网络出版: 2017 年7 月24 日 ∗国家自然科学基金项目(No. 21506042)和中央级公益性科研院所基本科研业务费(No. K⁃JBYWF⁃2015⁃T06， K⁃JBYWF⁃2015⁃G11)资助 The work was supported by the National Natural Science Foundation of China (No. 21506042) and the Fundamental Research Funds for the Central Public Welfare Scientific Institution (No. K⁃JBYWF⁃2015⁃T06， K⁃JBYWF⁃2015⁃G11). ∗∗Corresponding author e⁃mail: zhaoxu_miller@ 126. com http://www.progchem.ac.cn ProgressinChemistry，2017，29(7):796~808PDF Image | Extraction of Lithium from Salt Lake Brine

Product and Development Focus for Infinity Turbine
ORC Waste Heat Turbine and ORC System Build Plans: All turbine plans are $10,000 each. This allows you to build a system and then consider licensing for production after you have completed and tested a unit.Redox Flow Battery Technology: With the advent of the new USA tax credits for producing and selling batteries ($35/kW) we are focussing on a simple flow battery using shipping containers as the modular electrolyte storage units with tax credits up to $140,000 per system. Our main focus is on the salt battery. This battery can be used for both thermal and electrical storage applications. We call it the Cogeneration Battery or Cogen Battery. One project is converting salt (brine) based water conditioners to simultaneously produce power. In addition, there are many opportunities to extract Lithium from brine (salt lakes, groundwater, and producer water).Salt water or brine are huge sources for lithium. Most of the worlds lithium is acquired from a brine source. It's even in seawater in a low concentration. Brine is also a byproduct of huge powerplants, which can now use that as an electrolyte and a huge flow battery (which allows storage at the source).We welcome any business and equipment inquiries, as well as licensing our turbines for manufacturing.| CONTACT TEL: 608-238-6001 Email: greg@infinityturbine.com | RSS | AMP |
