The production of raw cement involves the extraction and procurement of raw materials like limestone and clay or iron ore. These materials are then crushed and finely ground to form the raw mix. The raw mix is then subjected to high-temperature heating in a kiln, reaching temperatures around 1400°C in a process called clinker.
