11.17 Lime Manufacturing

11.17.1 Process Description 1-5 Lime is the high-temperature product of the calcination of limestone. 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

Lime Production: Industry Profile

Limestone can be categorized as either high calcium or dolomitic. Pure high-calcium limestone is 100 percent calcium carbonate (100 percent calcite or aragonite). Generally, limestone of this purity does not occur naturally. High-quality, high-calcium limestone would actually contain 97 to 99 percent calcium carbonate and 1 to 3 percent impurities.

What are the influencing factors of calcination of limestone?

Calcium carbonate can be used to prepare calcium carbide, lime calcium powder, limestone, light calcium carbonate, nano-calcium carbonate and other products. It is an important industrial raw material. Calcination is a key process in limestone production. The quality of calcination has a great impact on the quality of subsequent products.
