Carbon mineralization sequesters CO₂ by reaction of alkaline earth metal bearing silicate and hydroxide minerals with CO₂ to form stable carbonate minerals. Seifritz (1990) proposed harnessing this natural process as a method for sequestration of anthropogenic CO₂. It was first studied in detail as an industrial process by Lackner et al. (1995), which is often referred to as “mineral carbonation.” Much of this early research aimed to capitalize on the globally abundant natural deposits of ultramafic and mafic rocks, which are rich in alkaline earth metals, in addition to the long-term stability of the resultant...
