Limestone is natural sedimentary rock deposit composed of calcium carbonate. All limestone mined by us falls under the classification of high calcium limestone.
Our mine produces good quality Limestone for Steel, Cement and Construction Grade. We currently have more than 50,000,000 metric tons in our reserves, and have the capacity to produce more than 2,500,000 metric tons per year.
High calcium limestone is utilized in the production of construction materials such as roofing shingles and asphalt paving. It is also used as an additive to animal feeds, in the production of glass and soil enhancement; in the wet scrubbing process for flue gas desulfurization for utilities and other industries and for mine safety in coal mining operations.
