A research team is close to patenting a new technique to extract lithium from brine that could revolutionize the lithium extraction process and potentially cut the production costs of a key component of lithium-ion batteries. ........ A team of researchers from Australia’s Monash University, Australia’s national science agency CSIRO, the University of Melbourne and the University of Texas at Austin have developed
a new filtering technology to extract lithium ions from brine. This technology has a much higher recovery rate than current extraction techniques and cuts the extraction process time down to just a few hours from several months to years in current lithium extraction. According to
EnergyX, the direct extraction via a membrane technology could extract lithium in a few days compared to 18 months in lithium evaporation ponds. In addition, lithium ponds use 18,000 gallons of freshwater per ton, while the new technology doesn’t use freshwater, potentially saving water resources in lithium brine-rich areas such as the so-called lithium triangle in Chile, Argentina and Bolivia. In price comparison, the direct membrane filtering of lithium, the so-called lithium refinery, costs half the cost of lithium evaporation ponds, EnergyX says.
