Abstract
This report from IEAGHG is a review of the current status of mineral carbonation using mine tailings consisting of rock fragments that are known to be reactive with CO2. Many key industrial metals including nickel, chromium and platinum group metals (PMG) are associated with magnesium, iron and calcium rich silicate minerals that are known to be reactive with CO2. The resultant carbonate minerals permanently lock CO2 into solid phases.
The key question is how rapid and effective is this process and can it be achieved economically without excessive additional energy. This review has critically investigated three decades of research on the subject as well as the most recent advances in industrial CO2 mineralisation.
