Steps in the Cement mining process: The mining process for cement consists of six main steps. Step 1: Raw Material Extraction: Limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale, and bauxite are the raw materials required to make cement. The ore rocks are mined and reduced to bits no larger than 6 inches.
