Cadmium occurs as a minor component in most zinc ores and is a byproduct of zinc production. Cadmium was used for a long time as a corrosion-resistant plating on steel, and cadmium compounds are used as red, orange and yellow pigments, to color glass, and to stabilize plastic.
Fortunately, small amounts of cadmium are found in zinc ores and most of the cadmium produced today is obtained as a byproduct of mining and refining zinc. Cadmium is a poisonous metal and its use is somewhat limited for this reason. Like zinc, cadmium can be electroplated to other materials to protect them from corrosion.
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. Relation to Mining

Its mining history has given rise to street names such as Hind Pits Lane, Hollow Road, and Comrade Avenue. The old mines have also meant that the soil is heavily contaminated by heavy metals such as cadmium. This was investigated in 1979. Concentrations of cadmium, lead and zinc in local crops were higher than would normally be expected.
2015-12-21· Cadmium (Cd) is a soft, ductile, silvery white metal that melts at 320.9°C and is present in the earth's crust at 0.1-0.5 parts per million. The most common cadmium MINERAL, greenockite (CdS), is generally found in zinc-bearing ores and is recovered as a by-product during processing.

Cadmium is an essential element in many forms of a new class of semi-conductor known as quantum dots. These advanced materials show promise in the areas of electronics, photo-voltaics and medical imaging. And finally in nature, a group at Princeton University a few years back showed that some marine diatons can substitute cadmium for zinc in the important enzyme carbonic anhydrase. This
History Cadmium is found under zinc in the periodic table, and it has similar properties. In 1787, chemists Karl Hermann and Friedrich Stromeyer separately discovered the new metal as an impurity in zinc carbonate. The name cadmium comes from the Latin word for calamine, which is zinc carbonate. Cadmium was not produced in large quantities
Nickel-cadmium (NiCd) Invented by Waldemar Jungner in 1899, the nickel-cadmium battery offered several advantages over lead acid, then the only other rechargeable battery; however, the materials for NiCd were expensive.
