  • Cadmium poisoning - Wikipedia

    Cadmium is a naturally occurring toxic heavy metal with common exposure in industrial workplaces, plant soils, and from smoking. Due to its low permissible exposure in humans, overexposure may occur even in situations where trace quantities of cadmium are found. Cadmium is used extensively in electroplating, although the nature of the operation does not generally lead to overexposure.

  • 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.

    Zinc (Zn) is known to interact with lead (Pb) and cadmium (Cd) reversing their toxicity and reducing their concentrations. However, lactating women are at high risk of developing Zn deficiency, which may result in Pb and Cd intoxication or increased exposure of breast-fed infants to Pb and Cd from breast milk.

  • Zinc and Cadmium - University of Denver

    Cadmium was only discovered in 1817 as an impurity in zinc by Stromeyer, who studied the deposits in lead and zinc furnaces called cadmia fornacis, and accordingly the metal was called cadmium. After iron, aluminium and copper, zinc is usually the fourth-most used metal, competing with lead.

    Cadmium (Cd) is a soft, malleable, bluish white metal found in zinc ores, and to a much lesser extent, in the cadmium mineral greenockite. Most of the cadmium produced today is obtained from zinc byproducts and recovered from spent nickel-cadmium batteries.

  • By-products – Nyrstar

    Cadmium. Cadmium is a soft, bluish-white, ductile metallic element that occurs in association with zinc ores. Its main use is in the production of nickel cadmium batteries. Copper. Nyrstar produces copper in concentrate and copper cathode. Copper is a soft, but tough metal, and it is an excellent conductor of heat and electricity.
