2.5. LithiumExtractionTechnologies 2.5.1. Overview For the past several decades, a combination of solar evaporation and carbonation has been mainly utilized to produce pure lithium compounds. However, this combination can be applied only to brine that has a relatively high concentration of lithium, roughly more than 500 mg/L. The evaporation method also takes approximately one year to concentrate lithium and subsequently precipitate lithium carbonate. Thus, other rapid processes have been considered and studied recently as shown in Table 2.11.46 This section reviews those technologies by considering some practical examples. Table 2.11 Technologies for lithium extraction from brine and their mechanism. Technology Solar evaporation Phosphate precipitation Mechanism Developer Conventional POSCO26,27 Lithium-containing solutions in ponds are concentrated by solar heating so that lithium carbonate can precipitate after adding soda ash (sodium carbonate). 2LiCl+Na2CO3 →Li2CO3 +2NaCl In place of soda ash, phosphoric acid is used to precipitate lithium. 3LiCl+H3PO4 →Li3PO4 +3HCl - 33 -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)
