    3/4/2020· Mining also creates knock-on effects — like water pollution, air pollution and vegetation loss as a result of soil eruption. This can lead to greater habitat loss beyond the immediate location. Habitat Destruction Caused By Mining Habitats can be restored after mining operations are finished, but some impacts will linger.

    and silver are among the most wasteful metals, with more than 99 percent of ore extracted ending up as waste. By contrast, iron mining is less wasteful, with approximately 60 percent of the ore extracted processed as waste (Da Rosa, 1997; Sampat, 2003). Disposing of such large quantities of waste poses tremendous challenges for the mining
