Effects on mining copper on the environment. Some effects of mining on the environment destroys forest and wetlands.It may mean that you have to cut down lots of trees just to get to the spot that has all the gold o r iron ore.Many mine require tailings dams to prevent waste being washed into the rivers.
Dec 12, 2018 On an average about 2.5 to 3 tonnes of mining waste has to be excavated per tonne of iron ore production, generating about 40 to 50 million of mining waste. Improper disposal of such a huge quantity of mining waste generates problem, causing severe environmental pollution (Hughes et al. 2015 Hudson-Edwards et al. 2011 ).
Mining can become environmentally sustainable 1 by developing and integrating practices that reduce the environmental impact of mining operations. These practices include measures such as reducing water and energy consumption, minimizing land disturbance and waste production, preventing soil, water, and air pollution at mine sites, and conducting successful mine closure and reclamation.
Environmental hazards are present during every step of the open-pit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose radioactive elements, asbestos-like minerals, and metallic dust. During separation, residual rock slurries, which are mixtures of pulverized rock and.
