ore minings effect on the environment

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the The molecular weight of CO2 is 44 g/mole, and that of air is 28.97 g/mole. The total mean mass of the atmosphere is approximately 510 15 tonnes. At the concentration of 400 ppm, the amount of CO 2 in the atmosphere by weight is 3,000 Gt of CO 2 (400 x 10-6 x 44/28.97 x 5 x 10 15).).

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water, environment, and communities.

Have you ever wondered just how sulfide-ore copper mines pollute their surrounding environments? It's a good question, because in order to understand the environmental impacts to the Boundary Waters Canoe Area Wilderness and Voyageurs National Park, we must first understand all of the ways sulfide-ore copper mining can cause harm to the surrounding lakes, streams, wetlands and forests

While cyanide is supposed to be carefully monitored to prevent its escape into the surround environment, spills do occur—especially when there's no one around to enforce mining regulations. The effects of poisoning can be widespread, especially when a waste-holding pool overflows or breaks, as it did in Guyana in August 1995.
