Integrating accelerated CO2 mineralizationCO2 mineralization with hydrometallurgical processes offers a promising strategy to reduce industrial carbon emissions while improving the sustainabilitySustainabilityof metalMetal extraction. Mineral carbonation converts CO2 into stable carbonates using divalent metalsMetallike magnesiumMagnesium (Mg), calcium (Ca), and iron (Fe). Although naturally slow, the reaction rate improves significantly under high-temperature, high-pressure conditions and with fine particle sizes—though industrial-scale implementation remains challenging. In hydrometallurgyHydrometallurgy, these same metalsMetal are often treated as impuritiesImpurities during extraction. Their reactivity with CO2 creates an opportunity for sequestration, turning a waste stream into a carbon sink. Moreover, mineral carbonation can unlock low-grade critical metalsCritical metalslike nickelNickeland cobaltCobalt embedded in the rock, enabling their recovery as valuable by-products. By aligning CO2 capture with metal extraction, this integrated approach improves economic viability, supports a circular resource model, and offers a scalable solution to decarbonize the metalMetal industry. This review provides an in-depth analysis of this strategy, addressing current technological challenges and outlining necessary future research.
