Carbon Mineralization and Lithium Extraction in Phyllosilicates under Different Temperatures and CO2 Pressures: Advancing Secure CO2 Storage and Utilization Strategies
The urgent need to mitigate anthropogenic CO2 emissions necessitates the advancement of robust, scalable, and safe CCUS technologies. This study demonstrates rapid and stable carbonate formation in biotite-rich systems within just 24 h of CO2 exposure. Through a series of controlled static reactor experiments, biotite samples were subjected to varying temperatures (18–40°C), pressures (6–74 bar), and reaction durations, revealing profound mineralogical transformations and geochemical dynamics. The interaction of biotite with CO2-rich brine conditions led to the release of cations─Mg, Fe, K, Ca, and Li─with the highest concentrations observed under supercritical CO2 conditions. XRD and SEM analyses identified the formation of stable carbonate minerals, including calcite, siderite, and magnesite, directly evidencing rapid CO2 mineralization. A discovery, first to be reported in the literature, was the formation of lithium deuteride and lithium fluoride, highlighting a novel pathway for lithium mineralization under mild conditions (30°C, 6 bar), where lithium, initially incorporated within the biotite structure (2038 mg/kg), becomes highly mobile during CO2-induced reactions. This finding opens a new geochemical pathway for lithium recovery from sedimentary formations, suggesting that vast lithium resources hosted in clay- and mica-rich siliciclastic deposits, such as those in the Thacker Pass lithium deposit in Nevada, could be effectively extracted through CO2-assisted geochemical treatments. In addition to lithium, the experiments revealed substantial mobilization of critical metals─Ni, Cu, Zn, and Cr, emphasizing both the potential for critical metal recovery and environmental risks associated with CO2 leakage into shallow aquifers. These findings redefine the role of phyllosilicates from passive CO2 containment structures to active carbon mineralization reactors, capable of facilitating permanent CO2 sequestration at unprecedented rates. Furthermore, the cooccurrence of lithium mobilization and mineralization introduces a dual benefit─secure CO2 sequestration coupled with sustainable lithium resource recovery, critical for the global energy transition.
