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.

Cadmium Used by Van Gogh, Edison and Junger Cadmium is present throughout the environment and is naturally occurring in both the Earth's water and crust. It was first isolated in Germany in 1817 as a by-product of zinc refining. It found use in the 1850's as a pigment used in paintings because of its brilliant yellow, orange, and red colours.
