Koch Technology Solutions (KTS) is pleased to share the testing results at Saltworks Technologies, Inc. in Richmond, Canada, and additional production of high-purity lithium carbonate (Li2CO3) using product solutions from the Century Lithium’s Lithium Extraction Facility (Pilot Plant) in Amargosa Valley, Nevada, USA. An extract of the results are summarised below, but the full press statement by Century Litium can be read here.
The solutions tested at Saltworks were derived from leaching of claystone from Century Lithium’s 100%-owned Clayton Valley Lithium Project (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 of Century Lithium said: “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 its Li-Pro™ system, and its integration into Century Lithium’s chloride-based leaching process.”
- Repeated production of high-purity (99.87%) battery-grade lithium carbonate
- Improved lithium concentrations in DLE eluent
- Reduced volume of solution in downstream treatment and recycling
- Potential to eliminate evaporation from the post DLE process flowsheet
- Active testing underway to further improve DLE eluent grade
Century Lithium collaborated with KTS and integrated its Li-Pro™ system into the DLE stage of the Pilot Plant. This work has increased the grades of the DLE eluent (intermediate lithium product solution) several fold. Testing with KTS is expected to continue through the 3rd quarter while KTS collects information to prepare an engineering design and cost estimate for a full-scale deployment of Li-Pro™ system which will supplement Century Lithium’s Feasibility Study.
