Mining Water for all

Chemicals used by mining companies can also leach out of the mine site into nearby bodies of water. These chemicals are found in the tailings, the waste left over after rock is separated from the ore. Cyanide, which causes heart, brain, and nerve damage [13], and sulfuric acid, which can kill wildlife unable to adjust to the acidity, are two examples of chemicals used to help separate the ore from the mineral [3]. Cyanide and sulfuric acid are used
