Metal Mining In Land Fills Problems

Landfill mining operations began in November 2011. Between December 2011 and March 2015, 34,352 Mt of ferrous and non-ferrous metals were recovered and shipped for recycling, which consisted of metals 125 mm (5.2%), 50-125 mm (85.9%), 50mm (3.4%), zorba (4.6%), and mixed products (0.8%). The conservative estimated value of the recovered metal

    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
