Saturday, April 25, 2020 has been on to find new techniques. There is no “tried & true” in Lithium extraction, it’s more like “tried & was frustrated” or “tried & made do”. The challenge is to short-cut long processing times dependent upon evaporating at high-altitude salares. However a bigger problem is in locations where evaporation is not so guaranteed and where weather conditions (i.e. rainfall) can reverse the progress of evaporation. All the oilfield brines in consideration are in locations unsuited to the utilisation of evaporation ponds, as are also the mine brines. Only those geothermal brines with electricity generating potential can hope to mobilise that factor to create carbon-neutral (and non-evaporative) separation/concentration processes. The magic bullet that many are seizing upon is Direct Lithium Extraction (DLE). Direct Lithium Extraction The DLE process is currently used by multiple commercially operating projects to extract Lithium from brines. It is not just unconventional modes that are adopters as the broader Lithium industry is shifting to DLE because: Lithium extraction in hours instead of months Not weather-dependent like evaporation, in increasingly unstable climate Ability to produce consistent chemical product for battery industry Spent brine re-injected into reservoir with no evaporation losses. No water stress unlike some salares projects The list of things that DLE solves is exactly those things that currently ail the brine space (though one could add financing and isolated locations as problems the no technology will solve for the salares). The other issue pending in the brine is the plethora of different weightings of minerals in the brines, running the whole gamut from borates to magnesium. The latter in particular is a particular problem with deposits like the Salar de Uyuni in Bolivia having that as its main challenge. Although it is the biggest lithium resource in the world, the Salar de Uyuni has a high content of magnesium making it uneconomic to extract by current methods. Therefore technology to process brines with a high ratio of magnesium or other impurities to lithium are somewhat of a Holy Grail in the battery metals space. Using current processing technology for these brines, lithium yields at Uyuni would be low from solar evaporation and operating costs from reagent use would be very high. On the following page can be seen a graphic that shows just a few of the principal technologies for DLE under development. At the bottom can be seen the main parties either developing the technologies or showcasing it in their projects.

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 |
