Effects of Gold Mining on the Environment Sciencing

Some gold can be found by panning in rivers; heavy gold will remain in the pan, whereas lighter rocks and minerals float out. This small-scale form of gold mining has little effect on the body of water, but the large-scale 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

Geological and Geographical Characteristics of Gold Mines

Gold deposits are found in different types of rocks and geologic formations, falling into two mining categories: lode (primary) and placer (secondary). Lode deposits are contained within surrounding rock whereas placer deposits are dust particles contained in streams and stream beds. Geographically, gold can be found on all seven continents, and the world's oceans also contain vast amounts of

How Does Mining Affect the Environment? Reference

Mining affects the environment by exposing radioactive elements, removing topsoil, increasing the risk of contamination of nearby ground and surface water sources, and acidification of the surrounding environment. Other effects include the disruption of existing ecosystems, damaging landscapes by creating erosion and depletion of surrounding freshwater sources.

The Effects of Mining on the Ecosystem Sciencing

Soil compaction is one of the most severe effects mining has on ecosystems. Compaction is often the result of bulldozers and other pieces of large machinery moving across the landscape, often for many years while the mining is still in operation. As the soil is compacted, there are fewer pore spaces for oxygen and water to move through the soil profile, minimizing the potential for plant

What Is The Environmental Impact Of The Mining Industry

Mining is the extraction of minerals and other geological materials of economic value from deposits on the Earth. Mining adversely affects the environment by inducing loss of biodiversity, soil erosion, and contamination of surface water, groundwater, and soil. Mining can also trigger the formation of sinkholes. The leakage of chemicals from mining sites can also have detrimental effects on

The Effects of Gold Mining on the Environment

The greatest environmental concern in association with gold mining relates to the altering of the environmental landscape created by mines. The Surface Mining Control and Reclamation Act of 1977 was passed to require mining sites to be restored to their original contours. The act also requires a mining operator to submit a restoration plan of the land and a plan for mitigating acid mine
