In sweeping process with acidic solution, the magnesium could be swept more than the case with deionized water similar to the previous results. The final concentrations of the overall process are given in Table 3.56. Table 3.56 The comparison of the boron clay extract and elution solution composition after sweeping with acidic water The composition Clay extract conc. Elution solution conc. Change of concentration Li (ppm) 412.0 521.4 Increased by 1.06 folds Na (ppm) 4964.0 49.7 Decreased by 100 folds K (ppm) 584.0 12.3 Decreased by 48 folds Mg (ppm) 15972.0 656.6 Decreased by 24 folds When Table 3.54 and Table 3.56 are compared, it is obviously seen that using an acidic sweeping solution helps to remove more foreign ions from the column and increase the lithium/foreign ion ratio, thus increase the overall separation efficiency. However, higher magnesium ion concentration than lithium ion concentration in clay extract seems to be a problem for recovery of pure lithium carbonate in a real process. A repetition of the overall process would probably decrease the magnesium concentration and increase the lithium concentration however an additional separation unit must be utilized in order to get rid of magnesium content in the resulting lithium chloride rich solution. After the analysis of column experiments done in Section 3.4, the following conclusions can be written: - Lithium was obviously separated by adsorbents selectively compared to foreign ions Na, K and Mg. - Foreign ions were also adsorbed by PSMA content in the beads partially. - High foreign ion content in feed solution suppressed the capacity of LiMnO beads. - In sweeping operation, huge amount of Na, K and Mg ions could be swept through the column. 124PDF Image | SEPARATION OF LITHIUM FROM 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 (Standard Web Page)
