What Are the Different Ways That Minerals Can Be Mined

Surface or opencast mining is the easiest way to produce a mineral ore when the deposits of economically valuable minerals lie close to the surface. Miners first remove the vegetation and soil cover above a mineral body. They remove further rock cover with explosives that create an open pit. Quarries are open-pit mines that produce building materials.
