Boron and magnesium removal follow the evaporation. Magnesium is rejected by adding a base to precipitate magnesium hydroxide. During this step, magnesium and calcium precipitates and are removed from brine as hydroxides. Other monovalent cations remain in solution because of the difference of the solubility of their hydroxide in Table 2.9. Lithium carbonate is finally precipitated by adding soda ash Na2CO3 and then dried. As magnesium and calcium are removed beforehand, only lithium precipitates as lithium carbonate. Some sodium and potassium ions remain in solution, but these species can be ignored due to the solubility difference of their carbonate salts in Table 2.10. This lithium carbonate is a product itself and can be a source of other lithium compounds like lithium hydroxide LiOH.

Figure 2.13 is the process flow of Salar de Atacama, Chile. After the evaporation step, boron is removed by SX and magnesium is precipitated by lime. - 24 -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 |
