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. Relation to Mining. Cadmium rarely appears in nature and is most commonly sourced by its removal from zinc metals during the refining process.
Description Cadmium (Cd) is a very soft, silvery-white metallic element that can be cut with a knife.
