    Stone preparation comprises primary and secondary crushing. Screening ensures grading of the product into its respective grain sizes. If required, stone washing uses recycled water that is usually obtained from settling ponds. Following the crushing process, intermediate stone stockpiling guarantees a steady supply of stone to the downstream processes.

  • Lime Production: Profile

    Limestone can be categorized as either high calcium or dolomitic. Pure high-calcium limestone is 100 percent calcium carbonate (100 percent calcite or aragonite). Generally, limestone of this purity does not occur naturally. High-quality, high-calcium limestone would actually contain 97 to 99 percent calcium carbonate and 1 to 3 percent impurities.
