Influence of Ball Milling on CaO Crystal Growth During

The multicycle CO 2 capture performance of CaO derived from the calcination of ball-milled limestone and dolomite have been tested under high temperature and high CO 2 concentration environment for the first time. Here it is shown that the CO 2 capture capacity of CaO is inversely related to the milling power applied to the starting mineral and the size of nascent CaO nanocrystals.
