Extraction and Preparation of Raw Materials. The main raw materials (limestone, clay chalk or basalt) are quarried from natural rocks. They are crushed and transferred to pre-blending storage where other substances (such as sand, iron ore, bauxite, shale, slag, fly ash) are added to get the desired chemical composition.
