Cadmium Statistics and Information - usgs.gov

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 - Elements Database

Cadmium is also released through manufacturing and other human activities. Because sufficient quantities of cadmium are produced as a byproduct, cadmium ores are not explored. The mining sites are those where zinc is extracted, and the smelting of this metallic element from sphelerite, which is its ore, produces cadmium as a byproduct.

It's Elemental - The Element Cadmium

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.
