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 has many chemical 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 (Cd) is a soft, malleable, bluish white metal found in zinc ores, and to a much lesser extent, in the cadmium mineral greenockite. In 2011, U.S. production of cadmium was estimated at 600 metric tons, down approximately 40% from the production levels 20 years ago (1992). Most of the cadmium produced today is obtained from zinc byproducts and recovered from spent nickel-cadmium batteries.
1.1 PHASES OF A MINING PROJECT There are different phases of a mining project, beginning with mineral ore exploration and ending with the post-closure period. What follows are the typical phases of a proposed mining project. Each phase of mining is associated with different sets of environmental impacts. 1.1.1 Exploration
Mar 03, 2011· Cadmium is a natural element in the earth's crust. It is usually found as a mineral combined with other elements such as oxygen (cadmium oxide), chlorine (cadmium chloride), or sulfur (cadmium sulfate, cadmium sulfide). All soils and rocks, including coal and mineral fertilizers, contain some cadmium. Most cadmium used in the United States is extracted during the production of …
production of secondary cadmium is increasing. The amount of cadmium that is recycled, however, is difﬁcult to estimate for a number of reasons. For example, cadmium from baghouse dust, which is generated at lead and copper smelters, enters the primary cadmium production …
Cadmium deposits are documented at "Cinkur Mine." Cadmium is present at a grade sufficient to have a strong effect on the economics of an excavation project. It may even be viable as the only commodity mined. At the time this deposit was surveyed, there was a tapped production. Mining opporations could be year-round, intermittent, or seasonal.
Toxic metals, including "heavy metals," are individual metals and metal compounds that negatively affect people's health. Some toxic, semi-metallic elements, including arsenic and selenium, are discussed in this page. In very small amounts, many of these metals are necessary to support life. However, in larger amounts, they become toxic.
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.
Cadmium is used in the manufacture of batteries, electrical conductors and metal plating. Cadmium is also a byproduct of the mining and processing of iron, nickel and other metals and can be toxic to welders and industrial workers, producing a syndrome due to inhalation of excessive amounts known as cadmium fume fever.
