Limestone, applied as a slurry, which is a mixture of minutely crushed limestone and water, helps to prevent sulfur dioxide from escaping through the plant's smokestack. The limestone traps the sulfur dioxide gas in the wet slurry with calcium and oxygen and makes the pollutant a removable solid waste.

Mining describes the digging-up and removal of ore-containing rocks, either from large surface pits or underground workings. This run of mine (ROM) material is then processed to separate the valuable mineral from the unusable gangue. This second stage is known as mineral processing and will comprise some combination of crushing, screening ...
Any person, firm or corporation engaged in or controlling commercial surface mining of industrial minerals in areas opened on or after Jan. 1, 1972, must obtain a permit from the Missouri Mining Commission, in accordance with section 444.770.1 and section 444.770.2 RSMo..

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.
