Here are some of the effects of dirty gold mining practices. How Gold Mines Impact Local Ecosystems. Gold is usually mined in enormous, open pits. Some of these gigantic craters can even be seen from outer space. Of course, much habitat destruction takes place when one of these mines is created. Local ecosystems are disrupted, affecting the
Gold is most commonly mined in open pits dug specifically for that purpose. Even in the richest of mines, the gold content is a tiny fraction of the material dug up. Gold mining creates large amounts of waste rock, more than almost any other type of mining. This is because of the relative rarity of gold, with almost all large deposits easily
