Open-pit mining is one of several non-tunnel approaches to mining that gives miners ready access to minerals and stone near Earth’s surface. Explosives help create massive, canyon-like holes. Heavy machinery refines the holes into workable pits and extracts the valuable materials that large trucks then cart away. Solid and liquid waste are usually kept at disposal sites near the pit. | Open-pit mining is one of several non-tunnel approaches to mining that gives miners ready access to minerals and stone near Earth’s surface.

Mining — the extraction of minerals from the earth — has deep roots in Wisconsin. For millennia, Native Americans living near Lake Superior used the region’s abundant copper supply to forge tools, weapons, and jewelry, developing what is now called the Old Copper Culture. And beginning in the early 1800s, Wisconsin’s accessible lead deposits in the southwest part of the state attracted immigrants and helped to fuel the nation’s early growth. | |||
