Lime Production from Limestone

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.

Emissions from the Cement Industry

 · The direct emissions of cement occur through a chemical process called calcination. Calcination occurs when limestone, which is made of calcium carbonate, is heated, breaking down into calcium oxide and CO 2. This process accounts for ~50 percent of all emissions from cement production.
