Li2CO3 from brine Purities of greater than 99.9% for battery-quality lithium carbonate have been achieved using a proprietary artificial-intelligence-powered crystallization technology developed by Standard Lithium Ltd. (Vancouver, B.C.; www.standardlithium.com). The total cation contaminant levels were reduced from nearly 2,500 parts per million (ppm) to less than 139 ppm in the crystallization. Optimization work for the crystallization process, known as SiFT, was conducted at the University of British Columbia, and supports separate work related to the ongoing commissioning of Standard Lithium’s LiSTR Direct Lithium Extraction demonstration plant in the Smackover brine region in south Arkansas (Chem. Eng., July 2018, p. 9; www.chemengonline.com/extracting-lithium-waste-brine-without-ponds). The first-of-its-kind demonstration plant will use the Standard Lithium’s proprietary technology to selectively extract lithium from tailbrine that comes from a nearby Lanxess facility.
