What Is Surface Mining?

Subsurface mining is highly effective for mineral and metal deposits far below the earth's surface. Surface mining removes overburden, which is the dirt, rock, and vegetation on top of the mineral deposit. Once they unearth the deposit, miners can extract large amounts of matter relatively quickly. This method works best for deposits close to ...
