Sulphide of cadmium is used as a pigment (cadmium yellow); and the metal and some of its salts are useful reagents.
Overall level of Cd in soil samples lies between 78 and 527 ng/g while cadmium concentration in different vegetations varied in the range of – ng g−1. Concentrations of copper in soil and plant samples were found in the range of – mg kg−1 for soil and – mg kg−1 for plants.

Zinc Concentrate Roasting Cadmium. Cadmium is not the principal recoverable constituent in any ore, but it does occur at a ratio of about 1:200 with zinc. If lead and zinc are considered major products, then the major metal byproduct of the zinc industry was the more than 3 million pounds of cadmium produced in the United States in 1978 (15).
