Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.
