| Abstract Scope |
Direct Lithium Extraction is an immerging field, working to access lithium from the normal lithium sources without relying on energy intensive or time-consuming concentration steps. However, like any chemical process there are waste streams to deal with. From sources such as geothermal brines lithium is found alongside substantial amounts of transition metals that if recovered could turn a common waste stream into a value stream. By employing efficient membrane solvent extraction technology, zinc and manganese were selectively extracted from a real-world mixed metal waste stream. Both metals were separately recovered into a sulfuric acid solution with a cation purities of 98%+ and recoveries of 78% and 56% for zinc and manganese respectively. Factors affecting separations, recovery, and extraction rate were explored. |
