Mineral Carbonation - an overview | ScienceDirect Topics
This process is still in the research and experimental stage (Folger, 2013b). A commercial process would require mining, crushing, and milling of the mineral-bearing ores and their transport to a processing plant receiving a CO 2 stream from a power plant. The carbonation energy would be 30–50% of the power plant output.
