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.
