11.17 Lime Manufacturing
Although limestone deposits are found in every state, only a small portion is pure enough for industrial lime manufacturing. To be classified as limestone, the rock must contain at least 50 percent calcium carbonate. When the rock contains 30 to 45 percent magnesium carbonate, it is referred to as dolomite, or dolomitic limestone. Lime can also be

limestone calcium carbonate process
Calcium carbonate (limestone) is heated to form calcium oxide (quicklime) and carbon dioxide: It is an endothermic reaction and the equilibrium lies far to the left at low temperatures. Only at about 1200 K does the partial pressure of carbon dioxide exceed atmospheric pressure and the decomposition proceeds to completion.

A Look Into Carving Limestone
Limestone originates in the ocean, and is composed mostly of calcium carbonate. Calcium carbonate appears chalky and powdery, and gives limestone its malleable qualities. Because limestone is such a soft yet durable stone, it's ideal for carving! The Carving Process. Limestone is soft enough that it's relatively easy to carve.
