Summary and Objectives This chapter firstly focused on lithium chemistry from a scientific point of view. Second, the lithium market was reviewed in order to grasp supply and demand in the future. Lithium production was then reviewed from types of deposit to processes and technologies. Out of the technologies reviewed, this thesis focused on ion exchange resin and ferric phosphate reduction. The following summarizes the development of each technology and objectives for this research. Ion exchange resin probably has the longest history as a rapid lithium recovery process. Although this method is a conventional method to recover metal ions from solutions, lithium is much more challenging to adsorb selectively than other metal ions. The reason is that, in brine, a much higher concentration of sodium, potassium, calcium and magnesium ions are present (sometimes 100 times as high as lithium concentration in mol/L), and these ions have a stronger affinity than lithium to general cation exchange resins. Despite the unfavorable conditions for ion exchange resins, in the 1980s, Dow Chemical in the US invented aluminum-loaded resins which can adsorb lithium selectively from brine.5–7 However, as the invention needs some special conditions to be carried out and the selectivity is not so high, it has not yet been applied to a practical situation. Since then, there are fewer promising reports about lithium-selective ion exchange resins for brine while a lot of new types of resins have been developed like chelating resins. Therefore, this thesis tested a wide variety of commercial resins from various producers and summarized the current situation of ion exchange resins around lithium extraction from brine. Ferric phosphate is a relatively new adsorbent for lithium extraction from brine. While - 56 - (2.22)PDF Image | LITHIUM EXTRACTION FROM BRINE using ion resin

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 (Standard Web Page)
