  • Leaching   Mining Fundamentals

    Leaching Mining Fundamentals

    Leaching is a chemical process in mining for extracting valuable minerals from the ore. Leaching also takes place in nature where the rocks are dissolved by water. Post leaching, the rocks areleft with smaller proportion of minerals that they originally contained.

    Environmental Risks of Mining

    Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.
