2021-12-12 · Cadmium (Cd) is a very soft, silvery-white metallic element that can be cut with a knife. Cadmium has many chemical similarities to zinc and is often recovered from the primary zinc ore sphalerite. The single most important use of cadmium is in the production of nickel-cadmium (Ni-Cad) batteries.
