Globally, metal mining is one of the biggest sources of air pollution. A UNEP study finds that artisinal gold mining to be the leading source of human-caused mercury emissions. Smelting of metals, including gold, is a primary source of arsenic emissions and other toxins globally; To extract metal, ore is placed in a smelter, a type of furnace.

 — The preliminary study of streams and rivers from the Roşia Montană area revealed that the concntration of heavy metals— Cd, Mn, Cu, Pb, and Zn—are above accepted limits. The gold extraction method is based on flotation. The most important pollution sources are mine tailings. The determinations were performed for samples …

Mining lower grade ore requires the extraction and processing of much more ore to get the same amount of gold. Partially due to cyanide, modern mines are. much larger than before cyanide was used; create vast open pits; and; produce huge quantities of waste. More than 20 tons of mine waste are generated to produce enough gold for a typical ring.

The soil pollution created by mining operations is another threat to wildlife and human health. Frequently, valuable ores run through rocks containing sulfides, and exposing ...

 — History of Mining in Ghana. There is evidence of gold extraction activities in Ghana as far back as the 7th and 8th centuries A.D., as gold deposits attracted Arab traders into the country.7 These activities were strategically located along rivers where sediments believed to contain deposits of gold were washed constantly to separate the gold …
