Mineral Resources Definition, Types, Use and Exploitation
Definition A mineral is a pure inorganic substance that occurs naturally in the earth's crust. All of the Earth's crust, except the rather small proportion of the crust that contains organic material, is made up of minerals. Some minerals consist of a single element such as gold, silver, diamond (carbon), and sulphur.
Environmental Hazards of Limestone Mining Sciencing
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. Mining in the karst can lower the water table, which removes the support of rock that overlies water-filled caverns, which can create
The result is a mineralogically complex and very diverse mixture of calc-silicate minerals with calcite. Skarns are often mined because they contain valuable ore minerals. Skarns are too rich in silicate minerals to be called marble and sometimes they contain no carbonate minerals at all (used up in metamorphic reactions).
