  • Process for comminuting and activating limestone by reaction with CO.sub.2
    Patent number: 4272498
    Abstract: The present invention relates to a non-mechanical method of converting coarsely ground limestone to a very fine powder. A slurry of ground calcium carbonate or limestone is contacted with carbon dioxide gas at high pressure to convert the solids in the slurry to an unstable form. The carbon dioxide pressure is then instantaneously released to form a slurry of activated calcium carbonate particles substantially reduced in size. This activated calcium carbonate slurry may be used to scrub flue gases.
