Preparation of Ferric Phosphate Ferric phosphate powder was prepared in two different ways before a series of lithium extraction experiments because there is no commercial reagent of ferric phosphate. One was dehydration of ferric phosphate dihydrate (FePO4·2H2O, FPD) and the other was oxidation of battery-grade lithium iron phosphate (LiFePO4, LFP). First, the dehydration of FPD was done by calcination. FPD powder was put into a crucible and calcined for 2 hours at 300–600 °C in the electric furnace. Second, oxidation of LFP was treated chemically by potassium persulfate (K2S2O8) in aqueous solution. Equation (3.5) is the oxidation reaction and LFP and PS react in the ratio of 2:1. 2LiFePO4 +K2S2O8 →2FePO4+Li2SO4+K2SO4 (3.5) Here in this experiment, in order to oxidize LFP completely, LFP and PS were reacted in the ratio of 1:1. Specifically, 370 mL of 0.2 M PS solution was prepared in an Erlenmeyer flask and 0.2 M of LFP powder (11.67 g/370 mL) was put into the solution. Then, it was shaken on the shaker for 24 hours at 220 rpm and ambient temperature. After 24 hours, the powder was vacuum filtered and dried at 60–65 °C for further experiments and XRD analysis and acid digestion as well. The solution was also recovered and diluted 100 times in solution with 2% of nitric acid (HNO3) for ICP analysis - 69 -PDF Image | LITHIUM EXTRACTION FROM BRINE using ion resin

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)
