Figure 3. Lithium extraction process of Schultze and Bauer (1984) Research on minerals recoverable from geothermal brines in the United States was further advanced by the private sector when Salton Sea geothermal operators began to explore opportunities to add revenue streams with minerals recovery, though these efforts were not initially focused on lithium. CalEnergy developed a process to recover zinc from geothermal fluid utilizing ion exchange, solvent extraction, electrowinning, and casting. After 10 months of running a pilot plant in 1998, CalEnergy planned to build a mineral recovery facility to process geothermal fluid from multiple power plants at a rate of 9 million kg/h and capable of producing 30,000 mt of Zn at 99.9% purity (Clutter 2000). Limited production began in 2002 and continued through 2004 before the project was shut down because of poor economic performance. 3.3 DOESupportofLithiumExtractionfromGeothermalBrines The U.S. Department of Energy Geothermal Technologies Office has supported multiple projects focused on extraction of lithium, and other minerals, from geothermal brines. Through the American Reinvestment and Recovery Act, DOE supported Simbol Inc.’s (also known as Simbol Mining and Simbol Materials) development of processes to mine lithium and other minerals from geothermal brines at Salton Sea, including deployment of a pilot mineral recovery plant at CalEnergy’s Elmore plant that later moved to EnergySource’s John L. Featherstone plant. 8 This report is available at no cost from the National Renewable Energy Laboratory (NREL) at www.nrel.gov/publications.PDF Image | Lithium Extraction from Geothermal Brines

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 |
