What are the environmental impacts of extracting metals?

What is the environmental impact of extracting material resources?

In short, raw material extraction and processing always impact on the environment, resulting as they do in soil degradation, water shortages, biodiversity loss, damage to ecosystem functions and global warming exacerbation.

What are the environmental impacts of extracting silver?

Mining and largest consumers

Most silver production results in large emissions of mercury to air, soil, and water. Where silver is extracted by small-scale miners, large quantities of mercury are used, resulting in large health and environmental damages.

What environmental impacts does mining have?

Mining: Environmental Impacts

Mining can pollute air and drinking water, harm wildlife and habitat, and permanently scar natural landscapes. Modern mines as well as abandoned mines are responsible for significant environmental damage throughout the West.

What are some environmental issues associated with the mining and processing of metals used to make electronic devices?

The mining of raw materials for electronic products—including silicon, aluminum, copper, lead, and gold—contributes to increased respiratory problems for workers, such as silicosis, tuberculosis, bronchitis, and lung cancer. Gold mines are the leading source of mercury air pollution in the U.S.

How does pollution affect the environment?

Air pollution can damage crops and trees in a variety of ways. Ground-level ozone can lead to reductions in agricultural crop and commercial forest yields, reduced growth and survivability of tree seedlings, and increased plant susceptibility to disease, pests and other environmental stresses (such as harsh weather).

What is the biggest environmental risk of mining quizlet?

Mining causes disturbed lands, oil spills and blowouts, and mine waste dumping. Processing produces solid wastes, pollutes the air, water, and soil, and produces radioactive material, using this causes thermal water pollution, solid and radioactive wastes, and health hazards.

What are the environmental impacts of iron ore mining?

The mining of iron ore is highly energy intensive and causes air pollution in the form of nitrous oxide, carbon dioxide, carbon monoxide, and sulfur dioxide from diesel generators, trucks and other equipment. The mining of iron ore also causes water pollution of heavy metals and acid that drains from the mines.

What are the environmental impacts of mining in Australia?

Mining poses a variety of environmental risks, including potential impacts on ground and surface water quantity and quality, air quality, biodiversity, landscape stability and climate change. Australia’s mining sector has the skill, technology and motivation necessary to manage and mitigate these risks.
