Banded iron formations, pyritic black shale, and gold

Banded iron formations (BIF) are predominantly Precambrian sedimentary rocks composed of alternating layers of iron-rich minerals (commonly hematite and magnetite, but also siderite, chlorite, and grunerite) and silica-rich minerals (e.g., quartz or chert) in which the Fe content of the entire rock is at least 15 wt. %. Although typically thought of as strictly Fe resources, such as in the

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.
