Argosy Minerals (ASX:AGY) reported positive results from evaporation and concentration tests at its Rincon lithium project in Argentina. The tests are part of the definitive feasibility study for a 12,000 tonne per annum operation.
The company ran pilot-scale mechanical evaporation tests using proprietary technology from an independent European provider. The process concentrated post-solvent extraction brine from about 1.3% lithium to a range of 4% to 5% lithium, reducing solution volumes and potentially improving downstream recovery.
Managing Director Jerko Zuvela said the results support the engineering and feasibility program needed to complete the DFS. “We are pleased to continue achieving successful testwork results,” he said. The tests confirmed stable performance under operating conditions relevant for commercial application.
