Using cleaner technology to produce sustainable lithium to meet global demand
The historical method of processing lithium brine is to use evaporation ponds – this requires a large land ‘footprint’ and can take up to 18 months to harvest the lithium. Recently, a process called Direct Lithium Extraction (DLE) has shown that lithium can be processed in a more time-efficient and environmentally responsible way.
There are approx. 9 DLE methods being trialled throughout South America.
Basic overview of Direct Lithium Extraction (DLE) process
DLE has several potential benefits
- Reducing the footprint of evaporation ponds
- Decreasing production times compared with conventional brine operation
- Increasing recoveries from ~40% to over 80%
Xantippe’s proposed DLE pathway
- Initial phase will be a R&D partnership, followed by a MoU
- To be determined by drilling programme in Argentina and sample availability
- Entering into a formal collaboration agreement by Q3 2022
