In cement production, limestone is a fundamental component, serving as the primary source of calcium carbonate. It is heated in kilns to produce lime, which then reacts with other materials to form clinker, a key ingredient in cement. This process ensures the strength and durability of the final cement product.

In power plants, limestone is utilized for flue gas desulfurization, where it reacts with sulfur dioxide in exhaust gases to produce gypsum. This process helps reduce emissions and mitigate environmental impact, enhancing the plant’s compliance with regulatory standards and promoting cleaner energy production.
