Mining operations by their very nature have major impacts, positive and negative, on the local area and on local communities. They are usually in remote places and the people affected are often isolated or neglected communities.
It is inevitable that mining operations will disturb the environment in a fairly dramatic way. Forest cover may have to be cut down to clear the site of the mine or for access roads. Tunnels or open-cut pits are dug. Overburden is removed and dumped nearby, usually to erode slowly into nearby streams and rivers. Tailings from the ore processing plant have to be put somewhere—preferably into an on-site tailings dam, but more likely straight into a river or the sea.
Mine tailings may contain some dangerous chemicals, but the major problem is usually the huge amounts of solid sediment that they put into the river system, and the effect this has on water quality and marine life. This can directly affect the livelihood of people liv
