Calcium carbonate is a compound that is commonly found in rocks, such as limestone, marble, and chalk. It is extracted by mining or quarrying pure limestone or marble, which are composed primarily of calcium carbonate. The rock is then crushed and ground into a fine powder.
The manufacturing process of calcium carbonate involves several steps. First, the limestone or marble is crushed into smaller particles. Then, it is heated in a kiln to produce carbon dioxide gas and calcium oxide, or quicklime. The quicklime is then combined with water to produce a slaked lime or calcium hydroxide.
The slaked lime is further processed by adding carbon dioxide gas to produce calcium carbonate precipitate. This process is known as carbonation. The calcium carbonate precipitate is then filtered, dried, and ground into a fine powder, which is the final product.
In some cases, calcium carbonate is also produced by precipitation from a calcium salt solution. This method involves adding a calcium salt, such as calcium chloride or calcium nitrate, to a solution containing carbonate ions. The calcium carbonate precipitate is then filtered, dried, and ground into a powder.
The manufacturing process of calcium carbonate from limestone is widely used in various industries. It is used as a filler in the production of paper, plastics, paints, and coatings. It is also used as a dietary supplement for calcium intake and as an antacid for treating heartburn and indigestion.
Overall, the manufacturing process of calcium carbonate from limestone involves crushing, heating, carbonation, filtration, drying, and grinding. This process allows for the production of a high-quality calcium carbonate powder that is used in various applications.
