This smallscale form of gold mining has little effect on the body of water, but the largescale practice of mining gold from ore can have tremendous negative effects on water quality.
Environmental impacts of mining largely depend on the methods used and the geological context that governs how easily the minerals can be separated from the ore material. Unlike gold mining, which often uses potentially toxic chemicals such as mercury and cyanide, gemstone mining does not depend on chemicals for extraction of the rough material.
