How Does Limestone Affect the Environment?

04/08/2015  While limestone itself doesn't affect the environment, limestone mining can have a negative impact. On the other hand, the environment can affect limestone by breaking it down. Limestone mining can pollute water and create sinkholes. When limestone dissolves while it's still in the ground, caves and gullies form, a natural phenomenon known as karst.

11/02/2021  Limestones enriched in phosphate by the chemical action of ocean waters constitute a principal source of raw materials for the fertilizer industry. When heated to temperatures of 900 to 1,000 °C (1,650 to 1,800 °F), limestones will dissociate calcium carbonate and yield carbon dioxide and lime, the latter having major applications in the manufacture of Limestone and in agriculture.

Limestone - Wikipedia

Limestone is a common type of carbonate sedimentary rock.It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes have likely been more ...

Lime Production: Industry 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.
