The mineral processing like grinding of limestone for cement industry and

calcite and soapstone for ceramic industry generate huge quantity of dust in

the atmosphere. It retards the process of infiltration of water into the soil

after it settles down on the land. In recent years, industrial effluents as waste

have become a major source of land and water pollution in many parts of the

country.
