All the information on Cadmium - Introduction

Cadmium is found principally in association with zinc sulfide based ores and, to a lesser degree, as an impurity in lead and copper ores. It is also found in sedimentary rocks at higher levels than in igneous or metamorphic rocks, with the exception of course of the nonferrous metallic ores of zinc, lead and copper.

Cadmium is an element. Its most abundant naturally-occurring isotope is non-radioactive. It is found in nature in mineral forms and is obtained for commercial uses principally from cadmium ore, called greenockite, which is commonly found in association with zinc ore. Commercial production of cadmium ore depends on the mining of zinc (ATSDR 1999).

Cadmium is a rare metal. The concentration of cadmium on the Earth is around 0.5 ppm (parts per million). Mostly it is present in the form of ores of zinc and sulfide. The sulfide ore of cadmium is termed as greenockite (CdS). Currently, cadmium is obtained from the mining, smelting and purification of ores of zinc sulfide, and copper sulfide.

Cadmium is a metal that appears soft, malleable, and bluish-white in its elemental form. While it is a relatively widespread element, it is rarely found on its own as a pure metal and more often forms complex compounds in zinc ores. It is mainly produced through the process of smelting, mining, and refining zinc, lead, and copper.
