Minerals can be extracted by mining, drilling or quarrying.
Mining is the process of extracting minerals from rocks buried under the earth’s surface. Meanwhile, in open-case mining, minerals that lie at shallow depths are extracted by removing the surface layer. At the same time, Shaft mining is the method in which deep bores, called shafts, are made to reach mineral deposits that lie at great depths. Also, drilling is the method used to bore deep wells so as to take out Petroleum and Natural gas that occur far below the earth’s surface. Finally, in the method known as quarrying, minerals that lie near the surface are just dug out.
