Chapter 6. Conclusion Lithium is now getting more and more attention from around the world as an essential material for various energy storage systems, especially for electric vehicles, and demand for lithium has been increasing rapidly. To meet the demand, lithium has been mined from ore minerals and brines. Since it is known that brines have more lithium reserves than ore minerals in the world, many researchers are now studying how to recovery lithium effectively from brine. The difficulty is that brine contains a high concentration of sodium, potassium, magnesium and calcium, which limit selective extraction of lithium. Conventionally, solar evaporation has been used to reject those cations into a solid phase and concentrate lithium in brine. However, as the evaporation process takes more than one year and is highly dependent on climatological conditions, a more rapid process is strongly desired for the accelerating demand. Therefore, many studies have investigated new rapid lithium recovery methods using ion exchange resin, solvent extraction, inorganic absorbents such as manganese oxide, titanium oxide and ferric phosphate, phosphate precipitation, nanofiltration, membrane electrolysis and so forth. This thesis focuses on two types of adsorbents: ion exchange (IX) resin and heterosite-type ferric phosphate (FP). First, IX resin was studied. More than twenty cation exchange resins were tested in both lithium chloride solution without any other metal cations and a mixed saline solution containing lithium, sodium, potassium, magnesium and calcium chloride. Sulfonate, iminodiacetate and aminomethylphosphonate resins successfully extracted lithium from the lithium chloride solution. The resins recovered 16.3–32.9 mg of lithium per one gram of dried resins. However, no resins could adsorb lithium strongly or selectively from the saline solution with less than 1 mg of lithium per one gram of dried resins in loading. This behavior was due to the lack of selectivity for lithium - 137 -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 | RSS | AMP |
