Limestone Mining. The Everglades sit on top of a bedrock of limestone. Limestone quarries, the dark rectangular shapes just west of the urban areas, provide about half of the rock used in Florida's construction. In this part of Florida, groundwater is very near the surface. So as the rock is mined, the quarry pits fill with water.
Two mines along the Ohio River in north-central Kentucky (Outer Bluegrass Region) are producing stone from the Camp Nelson Limestone for the manufacture of low-magnesium and high-calcium limes. The limes are used for flue-gas desulfurization at coal-fired power plants, and for steel-furnace flux, chemical manufacture, and water treatment.

Limestone mining isn't discussed as often as, say, fracking or oil drilling, but it has its fair share of risks and problems. Let's look at six top limestone mining issues. 1. Groundwater Contamination. Limestone is mined underground, but vital groundwater is located underground too. When there is a limestone mine near a groundwater source ...
3. Processing Chemicals Pollution. This kind of pollution occurs when chemical agents (such as cyanide or sulphuric acid used by mining companies to separate the target mineral from the ore) spill, leak, or leach from the mine site into nearby water bodies. These chemicals can be highly toxic to humans and wildlife. 4.
Some Issues in Limestone Mining. Limestone is most often mined from a quarry. However, underground limestone . mines are found at places in the central and eastern United States, especially in and near cities. Underground mining of lime - stone has some advantages over surface quarrying and will probably increase in the future.
