Cadmium Statistics and Information - USGS
Cadmium, a soft, malleable, ductile, bluish-white metal, was discovered in Germany in 1817, and Germany remained the only important producer for 100 years. Currently, a large percentage of global cadmium metal production takes place in Asia. Cadmium is generally recovered as a byproduct from zinc concentrates.

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.

Cadmium's abundance in the Earth's crust is about 0.2 part per million (ppm). Greenockite (CdS), the only cadmium mineral of importance, is not found in any isolated deposits, but is nearly always associated with sphalerite (ZnS). Cadmium is usually produced as a byproduct in the recovery of primary zinc from zinc ores.

Cadmium is produced mainly as a by-product of mining, smelting and refining of zinc and, to a lesser degree, as a by-product of lead and copper production. It is therefore primarily produced in relation to zinc production rather than direct cadmium demand. Global cadmium production almost doubled between 1950 and 1990.

Cadmium is used in low-melting alloys, especially solder. It is also used in electroplating, paint pigments (cadmium sulfide is the common pigment cadmium yellow) and rechargeable batteries (ni-cads). Cadmium absorbs neutrons and is used in the control rods that dampen nuclear reactions in fission reactors.
EXPOSURE TO CADMIUM: A MAJOR PUBLIC HEALTH CONCERN
Cadmium is relatively rare and there are no common cadmium ores. Therefore, the element is still commercially obtained today as a by-product of zinc mining. Cadmium sulfide is the most abundant compound in zinc ores. Because it is easy to insulate and clean, it is the main source of cadmium for industrial applications.
