When limestone (solid Caco,) is heated, it decomposes into lime (solid Cao) and carbon dioxide gas. This is an extremely useful industrial process of great antiquity, because powdered lime mixed with water is the basis for mortar and concrete
10.12.2019 Limestone calcination process with looping CO 2 as heat carrier CaCO 3 (s) decomposition is the main chemical reaction in limestone calcination, where CO 2 is generated along with the product CaO. Unlike the traditional technology which emits the CO 2 into the atmosphere directly, the LCPCLR system proposed in this paper can recover the CO 2 from the process.

Calcium carbonate is abundantly available in nature as limestone, chalkboard, or marble and CaCO 3 fillers from these minerals can be produced at very low cost. Three forms of CaCO 3 fillers are used arranged in the order of purity, they are dry processed, beneficiated, and precipitated. Calcium carbonate is considered a soft, nonabrasive filler.

Limestone is a sedimentary rock that is composed of the mineral calcite. When a drop of dilute hydrochloric acid is placed on this rock, it bubbles and fizzes as carbon dioxide is released. This reaction can only occur when a rock is composed of the mineral calcite (CaCO 3). Can you turn limestone into slate? This process is called metamorphism
