Mineral processing like grinding of limestone for cement industry, calcite and soapstone for ceramic industry, have three-fold adverse effects. The fine dust, generated and released in the atmosphere, leads to surface scaling of the adjacent land after it settles down, consequently the infiltration rate is reduced and the run-off increases.
Disposal of solid and liquid waste by industries on surrounding land or water bodies has also become a major cause of land degradation and water pollution. Industrial activities like grinding of limestone, calcite and soapstone, which release dust, retards water infiltration into the soil. Some steps for land conservation are: Afforestation,
However, underground limestone mines can be found in the central and eastern United States, especially near cities. In humid climates, limestone dissolves quickly and is carried away by water. This creates caves which can become weak and collapse. Underground mining of limestone can cause a cascading environmental impact.
