Copper Ore

Cadmium occurs naturally in the environment at low levels, usually with zinc, lead and copper ore deposits. It is one of the most toxic industrial and environmental heavy metals because of its long half-life and multifaceted deleterious effects (Domingo, 1994).High cadmium concentrations are often associated with industrial emission sources like mining and smelting operations.
