Impact of gold mining associated with mercury ...

This work considered the environmental impact of artisanal mining gold activity in the Migori-Transmara area (Kenya). From artisanal gold mining, mercury is released to the environment, thus contributing to degradation of soil and water bodies. High mercury contents have been quantified in soil (140 μg kg(-1)), sediment (430 μg kg(-1)) and tailings (8,900 μg kg(-1)), as expected. The ...

The environmental impact of gold production

The stages that contributed the most to gold’s environmental impact were mining and comminution (crushing and grinding of the ore). Electricity use was responsible for just over half of the GHG emissions. This indicates that attempts to lessen the environmental impact of gold production should focus on these two stages. Mining and comminution are highly dependent on the grade of gold ore, as ...

Effects Of Mining on the Environment and Human Health

Impacts of underground mining. Underground mining causes huge amounts of waste earth and rock to be brought to the surface – waste that often becomes toxic when it comes into contact with air and water. It causes subsidence as mines collapse and the land above it starts to sink. This causes serious damage to buildings. It lowers the water table, changing the flow of groundwater and streams ...

How Does Gold Mining Affect the Environment?

25/03/2020  Gold mining creates large amounts of waste rock, more than almost any other type of mining. This is because of the relative rarity of gold, with almost all large deposits easily obtained near the surface having already been extracted. The rocks in which gold is found tend to be high in sulfur compounds, and when exposed to air and water via the digging of large pits, these rocks easily leach ...
