Presentation Title CO2 Mineralization and Critical Battery Metals Recovery from Olivine and Nickel Laterites

On-Site Speaker (Planned) Fei Wang
Abstract Scope The global clean energy transition requires CO2 emission reduction with a concurrent increase in the global supply of critical battery metals. A process has been developed at the lab scale. The hydrometallurgical process achieves CO2 mineralization and selective battery metal recovery from olivine and laterites. The natural minerals are processed at modest temperature with a carbon dioxide pressure in a sodium bicarbonate solution containing soluble ligands enabling nickel and cobalt extraction. Iron and magnesium react with CO2 gas to form stable mineral carbonates for carbon dioxide sequestration. The leached nickel and cobalt are recovered by sulfide precipitation as high-value sulfides. The corresponding barren solution is recycled with no decrease in performance. The process consumes carbon dioxide and a source of sulfide. No additional acid or base is consumed in this novel process.
