Cadmium is a heavy metal that causes direct harm to humans in several forms. It is regularly found with other heavy metals such as zinc, copper, and lead. Concentrations increase due to soil disruption/volcanic activity and a byproduct of industrial processes.[1] Industrially, its use is best known for electroplating and in the production of …Web

Cadmium (Cd) is a soft, malleable, bluish white metal found in zinc ores, and to a much lesser extent, in the cadmium mineral greenockite. Most of the cadmium produced today is obtained from zinc byproducts and recovered from spent nickel-cadmium batteries. First discovered in Germany in 1817, cadmium found early use as a pigment because of its ...Web

Cadmium sits right below zinc on the periodic table and therefore shares many of its same chemical properties. In the environment it is distributed nearly everywhere we find zinc and therefore when we mine zinc, we consequently mine cadmium. When we galvanize (zinc treat) a nail or some other bit of steel, a little cadmium comes along for the ride.Web
