  • What happens before, during, and after mining? American

    Discovering metal-rich deposits commonly requires extensive searching, and exploration is the first step in the mining cycle. Once exploration geologists find an area with metals, they determine whether it is of sufficient size and richness to be mined profitably. If the deposit is rich enough, activities to extract the metals from the Earth begin.
