Century Lithium Corp. (TSXV: LCE | OTCQX: CYDVF | Frankfurt: C1Z) has reported assay results of the first lithium carbonate made at the newly commissioned lithium carbonate stage in the company’s lithium extraction facility (pilot plant) in Amargosa Valley, Nevada, USA.
The pilot plant is an integral part of the company’s 100%-owned Angel Island Project in Nevada. Assays received for five individual lots of lithium carbonate produced during the initial startup indicated purity of the lithium carbonate (Li2CO3) as high as 99.2%.
“For an initial run, these results are very encouraging,” said president and CEO Bill Willoughby. “Lithium carbonate greater than 99.5% purity is typically considered battery grade. These results show we are close and have identified steps to improve further. Also, importantly, where we previously shipped concentrated lithium solution to be treated offsite, we are now able to do this at the pilot plant and show we have an end-to-end process that works.”
During the startup, five 40L lots of concentrated lithium solution were treated in the lithium carbonate stage, which included precipitation with sodium carbonate, washing and drying of the 4kg of lithium carbonate produced from each lot.
Additionally, with input from Hargrove engineers and constructors, adjustments were made that resulted in decreased sodium and other impurities. Over the five lots treated, the purity of the final lithium carbonate increased in each test to a high of 99.2%. Calcium and magnesium were identified as the primary non-lithium constituents.
