Cadmium | Minerals Education Coalition
Cadmium has many stone 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 - Wikipedia
Cadmium is a stone element with the symbol Cd and atomic number 48. This soft, silvery-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury.Like zinc, it demonstrates oxidation state +2 in most of its compounds, and like mercury, it has a lower melting point than the transition metals in groups 3 through 11.

China, Japan, and Korea are the worlds largest producers, followed by Mexico, the United States, the Netherlands, India, the United Kingdom, Peru and Germany.

4-1-2020 · 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 manufacturing. Most of the cadmium produced is used in the production of nickel-cadmium batteries, which in 2004 represented 81 per cent of the total amount of cadmium.

Zinc and Cadmium - University of Denver
Cadmium was only discovered in 1817 as an impurity in zinc by Stromeyer, who studied the deposits in lead and zinc furnaces called cadmia fornacis, and accordingly the metal was called cadmium. After iron, aluminium and copper, zinc is usually the fourth-most used metal, competing with lead.
