Chilean company slashes water usage in lithium extraction
Summit Nanotech has announced a major milestone in water efficiency for lithium extraction, reinforcing its position as a global leader in sustainable direct lithium extraction (DLE) technology. Independent validation confirmed that Summit’s process uses about 30% less freshwater than evaporation ponds and 50% less than commercial DLE benchmarks, while maintaining high lithium recovery and product quality. Summit Nanotech’s process has delivered consistent performance across commercially viable lithium brine assets in the US, Argentina and Chile including, lithium recovery and impurity rejection within the 96-99% range. This significant advancement in freshwater usage is enabled by Summit’s proprietary flow sequencing method, which requires benchmark low make-up water compared with evaporation ponds and all other DLEs, including the most advanced ion exchange (IX)…
