Century Lithium Corp. (TSXV: LCE | OTCQX: CYDVF | Frankfurt: C1Z) has reported testing results at Saltworks Technologies, Inc. in Richmond, Canada, and additional production of high-purity lithium carbonate (Li2CO3) using product solutions from the company’s lithium extraction facility (pilot plant) in Amargosa Valley, Nevada, USA.
The solutions tested at Saltworks were derived from leaching of claystone from the company’s 100%-owned Clayton Valley Lithium Project in Nevada and processed at the pilot plant via direct lithium extraction (DLE) to produce an intermediate concentrated lithium solution (DLE eluent).
Bill Willoughby, president, and CEO, stated, “It is very positive to see consistency in our high-purity, 99.87%, lithium carbonate product grades from our pilot plant this year,”
“The highlight though, is the almost five-fold increase in lithium grade in the concentrated lithium solution generated at the pilot plant. This was achieved through collaboration with Koch Technology Solutions and their Li-ProTM system, and its integration into Century Lithium’s chloride-based leaching process.”
Saltworks has once again produced battery-grade lithium carbonate (Li2CO3) from the DLE eluent produced at the pilot plant.
The assays results were finalized by Saltworks and independently assayed by SGS Canada, Inc. These results show consistency in composition of both the DLE eluent produced by the pilot plant earlier in the year and the resulting Li2CO3 product produced by Saltworks, achieving 99.871% content versus 99.875% reported previously.
The company’s collaboration with KTS is underway, utilizing KTS’ Li-ProTM equipment in the DLE section of the pilot plant, where lithium is selectively recovered from the leach solution while deleterious elements are rejected. Testing with KTS is expected to continue through Q3 2023, while KTS collects information to prepare an engineering design and cost estimate for a full-scale deployment of Li-ProTM system which will supplement the company’s feasibility study.
