Research suggests new lithium source in pyrite

Lithium, known for its reactivity and essential role in lithium-ion batteries, is critical for sustainable energy technologies like electric vehicles and renewable energy storage systems. Given the surge in lithium demand, researchers are looking into less conventional sources beyond the primary ones such as pegmatites and volcanic clays.
A promising avenue is being explored by a team from West Virginia University, led by sedimentary geochemist Shailee Bhattacharya. Their research investigates the potential of recovering lithium from pyrite minerals found in shale, specifically from 15 middle-Devonian sedimentary rock samples in the Appalachian basin. Bhattacharya will present these findings at the European Geosciences Union (EGU) General Assembly 2024.
The team discovered significant lithium content in the pyrite minerals, a revelation given the limited geologic literature on lithium’s association with sulfur-rich pyrite. This discovery is part of broader efforts to develop lithium-sulfur batteries, which could potentially replace current lithium-ion models.
The study, while specific to certain U.S. geological samples, suggests that organic-rich shale could be a viable source of lithium. This method could offer a sustainable alternative to new mining operations, aligning with broader goals of energy conservation and environmental protection.
