  • Effects of large‐scale gold mining on migratory behavior

    Maintenance of migratory corridors with expansion of the existing mine is important to minimize impacts of mine expansion on the ability of these large mammals to move through the area (Berger 2004, Bolger et al 2008, Sawyer et al1 Introduction Gold mining has been carried out in the former Gold Coast, now Ghana, for centuries (OfosuMensah, 2011a)Artisanal gold mining started in the goldrich areas long before modern largescale gold mining (Hilson, 2002a) and was one of the mainstays of the numerous Akan states that developed in the forest belt of Ghana (Dumett, 1979, 1998; Kea,Gold in Ghana: The effects of changes in largescale

  • Effects of Gold Mining on the Environment Clean Mining

    The largescale practice of mining gold from ore can have tremendous negative effects on water quality Gold typically sits in ore and sediment that contains toxins such as mercury When rivers are dredged to mine large placer deposits of gold, these toxins float downstream and enter the food web, as they have done in California’s South YubaFor each new gold ring produced, largescale gold mining generates over 20 tons of waste contaminated with cyanide 22 On average, only 000001% of mined ore is refined into gold The remaining 999999% is waste most of which is highly toxic 23 Gold mining leads to high quantities of heavy metal pollution, including lead, arsenic, cadmium23 Statistics On Toxic Chemicals + Heavy Metals In Gold
