The environmental impact of gold mining on the environment includes water, air and noise pollution. The mining industry in South Africa is one of the largest in the world. It provides jobs for hundreds of thousands of people in the mining industry alone. The mining industry also indirectly provides jobs for about 400 000 with the goods and ...

The study of gold sites in the Migori Gold Belt, Kenya, revealed that the concentrations of heavy metals, mainly Hg, Pb and As are above acceptable levels. Tailings at the panning sites recorded values of 6.5–510 mg kg−1 Pb, 0.06–76.0 mg kg−1 As and 0.46–1920 mg kg−1 Hg. Stream sediments had values of 3.0–11075 mg kg−1 Pb, 0.014–1.87 mg kg−1 As and 0.28–348 mg kg−1 Hg ...

Environmentally Friendly Ways of Mining Gold . Innovative technology only gains mainstream acceptance if it can be implemented economically while not deviating too far from traditional practices. To this end scientists and researchers around the world have found ways to mitigate the environmental impact of the mining industry.
