  • What Are the Different Ways That Minerals Can Be Mined ...

    Mining is the process of mineral extraction from an ore or rock seam. 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 ...
