Mineral carbonation, a process of carbondioxide (CO 2) captured from the atmosphere or flue gases, is a way to sequestrate CO 2 safely and permanently. In this technology, CO 2 is chemically reacted with calcium, magnesium, sodium, and ironcontaining materials. The procedure is analogous to natural weathering processes, to form thermodynamically stable and environmentally harmless carbonate ...
