A novel method of small-scale column testing achieved a 90.2% lithium extraction rate under the direction of\n \n Willem Duyvesteyn\n \n , of Extractive Metallurgy Consultancy LLC, based in\n \n Reno, Nevada\n \n . Mr. Duyvesteyn utilized the facilities of McClelland Laboratories Inc. (\"McClelland\") in\n \n Sparks, Nevada\n \n for the metallurgical tests.\n \n \n \n \n \n \n \n \n \n \n \n Highlights of Gemini Metallurgical Testing\n \n \n \n \n \n Preliminary leaching test work was designed to focus on obtaining a lithium leach extraction of more than 80%. Early tests included a standard sulfuric acid leach, the re-leach of residues, a hot acid beaker leach of low and high-grade mineralization, and a gypsum/lime roast water leach;\n \n \n Following the use of various extraction methods an \"acid-bake\" step was implemented using concentrated sulfuric acid on moist lithium-in-sediment mineralization with average lithium values of approximately\n \n 1,100 parts per million (\"ppm\") lithium\n \n ;\n \n \n A one-meter-tall column was loaded with Gemini clay mineralization and an open-circuit system employed a two-step leaching system, which achieved a 90.2% lithium extraction over a 25-day period.\n \n \n \n The 90.2% lithium extraction rate achieved from the Gemini mineralization compares favourably with the average lithium extraction of 84% reported by Lithium Americas at its\n \n Thacker Pass\n \n lithium project (\n \n Source: Feasibilit...
