There are two methods of mining by which extraction of minerals can be done: Open cast mining and Shaft mining. Open cast miningIt is a mining technique in which material is extracted by digging a large hole rather than tunneling or bouring. When mineral ore are located at the shallow depth, they are taken out by removing the surface layer.
