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
Mining and smelting are important economic activities However mining-related industries are also some of the largest sources of environmental pollution from heavy metals China is one of the largest producers and consumers of lead and zinc in the world
28-10-2015Topic Extraction of zinc Zinc is a transition metal that occurs in the center of the periodic table The periodic table is a chart that shows how chemical elements are related to each other The space between Groups 2 and 13 is occupied by the transition metals These metals share many physical and chemical properties in common
Mining could also be crowding out agriculture through competition for key inputs This is particularly relevant since mining has been linked to land grabbings and increases in the cost of living in mining areas Either phenomenon could lead to an increase in agricultural input prices and production costs
