the extremely dilute concentration of lithium in sea water, it is supposed that Koreans will employ an additional technique like adsorption or ion exchange in addition to evaporation and precipitation. POSCO claims that the production time for lithium carbonate will be reduced to 8 hours from 12 months which also implies the utilization of additional processes other than evaporation and precipitation [40]. Lithium production processes in four different brines were described and listed below. 1.4.1 Clayton Valley, Nevada Production of lithium from this deposit was initiated in 1966 by Foote Chemicals. The plant changed hands to Chemetall in 1998 and now has a capacity of 6400 tons of lithium carbonate per year. The valley has a 400 ppm lithium concentration initially but after years of operation its lithium concentration now reduced to 160 ppm. The concentration of lithium and other major ions in Clayton Valley is listed in Table 1.5. Table 1.5 Clayton Valley, Brine Composition Concentration (ppm) Ion 1966 [41] Na 7.5 Concentration (ppm) 1998 [42] 4.69 K 1 0.4 Li 400 163 Mg 600 190 Ca 500 450 Cl 11.7 7.26 CO3 - 74 B - 67 Br - 23 In Clayton Valley, lithium production starts with the evaporation of water in large ponds. In the first four ponds, brine gets concentrated while some amount of calcite (calcium carbonate) and gypsum (calcium sulphate dihydrate) precipitates.

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)
