Effects of Gold Mining on the Environment Sciencing
Some gold can be found by panning in rivers; heavy gold will remain in the pan, whereas lighter rocks and minerals float out. This small-scale form of gold mining has little effect on the body of water, but the large-scale practice of mining gold from ore can have tremendous negative effects on water quality. Gold typically sits in ore and sediment that contains toxins such as mercury. When
