Palsdottir and Tester Figure 4: The results of the extraction experiments performed in this research. The variables modified were the temperature, pressure, and cation exchanger excess. From Figure 4 we see that modifying the pressure and temperature in the extraction system between 60°C and 85°C and 200 bars and 250 bars has little effect on the extraction of lithium or on the selectivity in the extraction towards lithium over sodium and magnesium. Modifying the cation exchanger excess however has a much larger effect. There is a significant co-extraction of both magnesium and sodium in every case. This co- extraction does not have to be a huge concern since in many cases sodium and magnesium concentrations can be lowered with post-processing before the production of lithium products. In spite of the co-extraction of other compounds we have developed a very fast and effective concentration process for lithium in geothermal brines. If better selectivity towards lithium over other compounds is necessary a process like this one could be coupled with other more selective processes that have been developed and function as a pre-concentration process. 5. Conclusions and Recommendations This research for the first time reports on the effectiveness of the selective extraction of lithium using crown ethers in ScCO2. We demonstrated that with properly selected crown ether and cation exchanger pairs, ScCO2 extraction of lithium is achievable. In addition, feasible selective extraction was also shown from solutions with high concentration of other cations such asPDF Image | Mining the Future Lithium

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 |
