Standard Lithium Ltd. announced that the company has produced its first quantity of battery quality (>99.56% purity) lithium carbonate. The battery quality lithium carbonate was produced at the Company's prototype Lithium Carbonate Crystallisation Pilot Plant operated by Saltworks Technologies Inc., at their facility in Richmond, British Columbia, Canada. Lithium Carbonate Crystallisation Pilot Plant: The prototype crystallisation plant was operated as a two-stage crystallisation process. The initial solids produced from the first run (as previously reported December 12, 2018), were re-solubilised and crystallised a second time. The solids produced from this second run (second stage as reported here) were then hot-washed, filtered and dried. The resulting lithium carbonate crystals were a fine free-flowing powder and were >99.56% pure. Despite the fact that the synthetic starting solution had more impurities than are anticipated to be present in the solution the upstream process will produce, lithium carbonate purity targets were met, giving a measure of comfort that the crystallisation process is robust. Additional optimisation is now being performed, and the technical team will also be adjusting the composition of the input feed stream so as to optimise how the two parts of Standard Lithium's proprietary technologies work together.
