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 nickelcadmium batteries First discovered in Germany in 1817
-
Cadmium is generally recovered as a byproduct from zinc concentrates Zinctocadmium ratios in typical zinc ores range from 2001 to 4001 Sphalerite ZnS the most economically significant zinc mineral commonly contains minor amounts of cadmium which shares certain similar chemical properties with zinc and often substitutes for zinc in the sphalerite crystal lattice
