Abstract

Recently, the global researchers focussed on CO 2 sequestration through mineral carbonation because of increasing severe atmospheric CO 2 levels that can be emitted from several resources and has lead to concerns about global warming. The possible emerging technology can contribute to the reduction of CO 2 emissions is CO 2 sequestration by mineral carbonation. Atmospheric CO 2 is sequestered with real mine tailings via accelerated carbonation of Mg-bearing minerals. The rate of carbon sequestration at some mine sites appears to be limited by the rate of CO 2 supply. If carbonation of bulk tailings were accelerated, large mines may have the capacity to sequester millions of tonnes of CO 2 annually, offsetting mine emissions. Some case studies, the possibilities for the integration of CO 2 mineral sequestration in real mine tailings by accelerated carbonation for CO 2 capture storage and utilization (CCUS) technologies will be presented
