    Methods Of Production Of Calcium Carbonate From Limestone

    which limestone, which is mostly calcium carbonate CaCO 3 is heated in a kiln to produce quick lime CaO. Carbon dioxide is a byproduct of this reaction and is usually emitted to the atmosphere. However, some facilities recover a portion of the emissions e.g. for use in sugar refining and precipitated calcium carbonate production. Get price
