The answer is the cement industry. Limestone plays two major roles in the cement manufacturing process, one is used as a raw material for cement clinker, and the other is used as a cement admixture. Limestone is one of the key raw materials of cement clinker. Around 80-90% of the raw material for the kiln feed is limestone.

The production of cement begins with preparation of the raw materials – limestone, gravel and clay, where they are grinded into fine powder. Cement clinker is then produced by adding the prepared limestone into a cement kiln at a temperature around 1450 degrees Celsius. This allows for the calcination of limestone into cement and CO 2.
