Cadmium has many chemical and physical properties that make it desirable for industrial and consumer applications: resistance to corrosion and chemicals, tolerance of high temperatures, a low melting point and excellent electrical conductivity. These properties make cadmium suitable for use in alloys, pigments, coatings, stabilizers and rechargeable nickelcadmium (NiCd) batteries, which are ...

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 corrosionresistant plating on steel, and cadmium compounds are used as red, orange and yellow pigments, to color glass, and to stabilize plastic.
Cadmium waste streams may also enter the air through () waste combustion and burning of fossil fuels. Because of regulations only little cadmium now enters the water through disposal of wastewater from s or industries. Another important source of cadmium emission is the production of artificial phosphate fertilizers.

May 12, 2008· It is released into the environment through mining and smelting, its use in various industrial processes, and enters the food chain from uptake by plants from contaminated soil or water. Sources of Cadmium: Cadmium has been widely dispersed into the environment through the air by its mining and smelting as well as by other manmade routes:
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.
Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have ...

The Nickel Mining Process. Nickel mining occurs through extractive metallurgy, which is a material science that covers various types of ore, the washing process, concentration and separation, chemical processes and the extraction process. One of the most wellknown purification processes is called the Mond Process, which is an extracting and ...
Cadmium is not the principal recoverable constituent in any ore, but it does occur at a ratio of about 1:200 with zinc. If lead and zinc are considered major products, then the major metal byproduct of the zinc industry was the more than 3 million pounds of cadmium produced in the United States in 1978 (15).
Cadmium is mainly a byproduct of beneficiating and refining of zinc metal from sulfide ore concentrates. Refining of zinc and its cadmium content, can be accomplished by treating the zinc concentrates and/or zincbearing secondary materials using either a hydrometallurgical or pyrometallurgical process.
Cadmium (Cd) is a soft, malleable, bluish white metal found in zinc ores, and to a much lesser extent, in the cadmium mineral greenockite. Most of the cadmium produced today is obtained from zinc byproducts and recovered from spent nickelcadmium batteries.

Cadmium is a low cost metal, easy to work with, and has similar characteristics to lead. Q: Why is cadmium a chemical of concern? A: Cadmium is a highly toxic substance, exposure to which can produce a wide range of health effects. Cadmium can replace zinc in the body and can bind strongly to certain biological systems, making it difficult to ...
mining and refining of cadmium Cadmium is a chemical element with symbol Cd and atomic number 48. This soft, bluish white .. Thus, cadmium is produced mainly as a byproduct of mining, smelting, and refining sulfidic ores of zinc, and, to a lesser degree, lead and copper.
