What Are the Different Ways That Minerals Can Be Mined

The minerals can range from precious metals and iron to gemstones and quartz. In ancient times, miners recognized a mineral rock formation from its outcrop at the surface. Modern mining technology uses geophysical techniques that involve measuring the magnetic, gravity and sonic responses of rocks above and around a prospective mineral ore body.
