A draft report confirming that the ACCELi (Accelerated Chemical Cavitation Extraction of Lithium) process performed as intended, yielding lithium phosphate solids with a purity of 94.2%. The third and final test run achieved a lithium recovery rate of 69.3%. The average concentration of lithium taken from the source tank across the three batch runs was 243mg/l. Each of the three test runs showed continuous improvement, with the equipment operating as designed. The ACCELi process selectively extracted lithium, barium, strontium, magnesium, and calcium based on their solubility, and precise chemical data, efficiently extracting these as saleable by-products.","length":836,"tagName":"p"},{"type":"text","content":"Accurate brine analyses were ultimately sourced for the last test from Isobrine Ltd. in Edmonton and they provided the necessary data to optimize dosing and improve ion removal before the lithium extraction stage.

This was in line with our expectation when considering, amongst other things input concentration, time on site and an initial delayed receipt of accurate chemical analytical results. Future improvements in purity and recovery are expected by ensuring accurate chemical analyses are readily available before each step of the process. We believe that the remaining lithium present in the brine after this final process can be recovered using additional stages or by being paired with an identified complime...
