Limestone is a source of calcium carbonate and is heated to convert the calcium carbonate into calcium oxide. This process is generally carried out in large rotary kilns or vertical shaft kilns where high temperature is required. Quicklime is produced in the calcination process, which can be crushed depending on it's use.

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.

Calcium oxide and the specific products derived from it are obtained by the process of calcination of calcium carbonate at high temperature. CaCO 3 + Heat → CaO + CO 2. Calcium oxide is an alkaline product that allows the regulation of many industrial processes. Its principal properties depend on its chemical composition and the thermal treatment that the mineral has been subjected to, which ...

Jul 31, 2020· Quicklime is also known as burnt lime, a reference to its manufacturing process, or simply lime. To make it, limestone (CaCO3) is broken up and shoveled into a kiln, which is heated to very high temperatures.The high temperatures release carbon dioxide (CO2) from the stone, turning it into calcium oxide. After it is cooled, the compound can be ground into a powder and packaged for sale.
