Cadmium | chemical element | Britannica.com

A rare element (about 0.2 gram per ton in Earth's crust), cadmium occurs in a few minerals and in small quantities in other ores, especially zinc ores, from which it is produced as a by-product. The chief zinc ore, zinc blende, or sphalerite, consists mainly of zinc sulfide, containing from 0.1 to 0.3 percent cadmium.

Cadmium | Define Cadmium at Dictionary.com

Cadmium is separated from zinc and other elements by repeated distillation of its ores. It is also produced by precipitates obtained from the liquors, during the electrolyte refining of zinc. Cadmium and its compounds are toxic in nature.

Cadmium | Minerals Education Coalition

Cadmium sulfide is a green solid. It occurs in nature with two different crystal structures as the rare minerals greenockite and hawleyite, but is more prevalent as an impurity substituent in the similarly structured zinc ores sphalerite and wurtzite, which are the major economic sources of cadmium.

All the information on Cadmium - Introduction

Cadmium (Cd) is a very soft, silvery-white metallic element that can be cut with a knife. 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.
