Irresponsible Mining Damages the Environment

Mining has a great effect on the quality of the air. Since mines need to blast through rock to get to an ore, dust may be produced in the process. Coal mines release methane, which contributes to environmental issues because it is a greenhouse gas. Methane is sometimes captured, but only where it is economically feasible to do so.

GCSE Metals | Revise Problems of Extraction from Ores

One major environmental problem with mining ores is what to do with the spoil (waste material from the mining) as this contains traces of the ore which is often toxic. When it rains, traces of the metals can leach out. This leaching can spread the toxic waste more widely into the environment. An example of this is from lead mining in Derbyshire.
