Cadmium Statistics And Information Usgs

Cadmium Statistics and Information. 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.

Mineral Commodity Profiles Cadmium

Cadmium was discovered in 1817 by Friedrich Stromeyer, who isolated it from an anomalously colored sample of zinc ore and named it cadmium after cadmeia, the ancient Greek name for zinc ore. ... then accounted for practically the entire world production of cadmium.

Toxic Metals Overview Occupational Safety And Health

Cadmium. Cadmium is an extremely toxic metal commonly found in industrial workplaces, particularly where any ore is being processed or smelted. Several deaths from acute exposure have occurred among welders who have unsuspectingly welded on cadmium-containing alloys or with silver solders.

Cadmium Toxicity Where Is Cadmium Found

Cadmium, a rare but widely dispersed element, is found naturally in the environment. Most cadmium ore (greenockite) exists as cadmium sulfide, is refined during zinc production, and occurs in association with zinc. It is released into the environment through mining and smelting, its

The Facts On Cadmium Dartmouth Toxic Metals

Most commercial cadmium is obtained as a byproduct of zinc ore refining, though cadmium can also be recovered from recycled materials such as nickel-cadmium batteries and metal scrap. The United States is the worlds primary producer of cadmium, generating an estimated 1,100 tons of the metal per year.

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, and also from some lead ores or complex copper - lead - zinc ores.

Cadmium Toxicity What Is Cadmium Environmental

Cadmium is an element. Its most abundant naturally-occurring isotope is non-radioactive. It is found in nature in mineral forms and is obtained for commercial uses principally from cadmium ore, called greenockite, which is commonly found in association with zinc ore. Commercial production of cadmium ore depends on the mining of zinc (ATSDR 1999).
