Aug 10, 2018· Sulfuric acid is sometimes produced when water interacts with tailings, or it can be a byproduct of ore processing. As a result, highly acidic water leaks from the tailings and disrupts aquatic life downstream. Tailings from copper and uranium mining often produce measurable levels of radioactivity.
Environmental impacts from fossil fuel pollution are rapidly increasing in regions that have the highest concentrations of fuels. There are multiple effects of mining fossil fuels. Drilling and mining practices take a substantial toll on local water sources, biologic life and natural resources.
Solutions to Mining Industry Risk Challenges ... Operational efficiencies have increased and, as many countries demand more and more commodities (including coal, copper and iron ore) to underpin the expansion of their infrastructure, the mining industry is once again thriving with commodity prices rising.

Exposure to chronic high levels of copper can increase risk factors for lung cancer and coronary heart disease. Studies of copper mine workers both pre and post mortem have detailed the risk of chronic copper exposure and broken the risk up by parts of the copper mining processes ( smeltering, converting, plating) (11,12,13,14). Figure 3.
This means that metal or mineral extraction results in problems and issues in balancing ecological, environmental, economic, social advantage factors. It doesn''t matter whether you are mining and processing iron ore or limestone, many of the advantages and disadvantages are common to these operations.
Jan 21, 2015· Copper is a reddish metal that occurs naturally in rock, soil, water, sediment, and, at low levels, air. Its average concentration in the earth''s crust is about 50 parts copper per million parts soil (ppm) or, stated another way, 50 grams of copper per 1,000,000 grams of soil ( ounces or pounds of copper per 2,200 pounds of soil).
