Figure 2 shows lithium distribution during brine evaporation process in both the simulation experiment and field sampling from different salt ponds. As brine concentrating lithium in aqueous phase was enrichened, the average concentration of lithium could reach a level of 500 mg/L. In residual brine, this was more than double the concentration in the original brine. The simulation experiments showed that the vast majority of lithium was retained in the aqueous phase and there Minerals 2017, 7, 57 5 of 12 was a positive correlation between lithium concentrations with brine enrichment degree.

Identification results of solid phase during the brine evaporation process. Lithium content in solid phase had no evident change (p > 0.05) during the brine concentration process until bischofite was precipitated.

It shows that the Magnesium-lithium ratio does not changed much in early evaporation stage (depicted in magenta and violet colors), but a larger change appears when the brine density value is more than 1.285 g/cm3 (depicted in blue and green colors). The magnesium-lithium ratio decreases sharply in the later stage of evaporation, especially when brine density is more than 1.345 g/cm3. Brine magnesium-lithium ratio decreases almost to half of initial value when the brine density is around 1.372 g/cm3 (depicted in red). The brine density value could represent the degree of brine concentration because brine density is proportional to the degree of evaporation. The greater the density value, the higher the degree of brine evaporation and lithium enrichment. As shown in Figure 3, the magnesium-lithium ratio remains at about the same level in the early evaporation stage, but a slight decrease appears when the brine density value is more than 1.28 g/cm3, almost the moment when carnallite crystalized. Thus, it can be deduced that the brine magnesium-lithium ratio decrease was caused by carnallite precipitation. This is because carnallite is a double salt that contains 8.64% magnesium and the precipitation led the magnesium ions to migrate to solid from aqueous. The magnesium-lithium ratio decreased sharply in the later stage of evaporation, especially when brine density was more than 1.34. The brine magnesium-lithium ratio value almost decreased half of its original value when the brine density reached 1.37 g/L.

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)
