Cadmium - GreenFacts

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. Other major uses of refined cadmium are: pigments for plastics, ceramics and,Cadmium | Minerals Education Coalition,Individuals and organizations have been reviewing cadmium's bioinorganic aspects for its toxicity. The most dangerous form of occupational exposure to cadmium is inhalation of fine dust and fumes, or ingestion of highly soluble cadmium compounds. Inhalation of cadmium fumes can result initially in metal fume fever, but may progress to chemical pneumonitis, pulmonary edema, and death. Cadmium is also an environmental hazard. Human exposure is primarily from fossil fuel combustion, ph…Cadmium - Wikipedia,Cadmium is primarily consumed for the production of rechargeable nickel cadmium batteries; other end uses include pigments, coatings and plating, and as stabilizers for plastics. Solar cell manufacturing may become another significant market for cadmium in the future.

Cadmium: processing-Metalpedia

Mining and beneficiation; Cadmium is mainly a byproduct of beneficiating and refining of zinc metal from sulfide ore concentrates. The mined zinc ores are crushed and ground to liberate the zinc sulfide particles from the waste host rock. The ground ore is usually treated by a differential flotation process to separate the zinc-bearing particles from the waste rock, yielding a high-grade zinc,The Facts on Cadmium | Dartmouth Toxic Metals,Humans play a significant role in creating concentrated sources of cadmium and releasing it into the environment through activities such as mining, smelting and refining metal ores — particularly zinc, lead and copper. Cadmium is also emitted into the atmosphere from fossil fuel burning, waste incineration and steel production. Soil and water near industrial areas or waste sites may contain,Cadmium resources, reserves and production-Metalpedia,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 (elemental symbol Cd and CAS registry number 7440-43-9) is a member, along with zinc and mercury, of Group 12 (CAS IIB) of the Periodic Table of the Elements. It is generally characterized as a soft, ductile, silver-white or bluish-white metal, and is listed as 64 th in relative abundance amongst the naturally occurring elements.

Cadmium | The Canadian Encyclopedia

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.
