Cadmium is produced mainly as a by-product of mining, smelting and refining of zinc and, to a lesser degree, as a by-product of lead and copper production. It is therefore primarily produced in relation to zinc production rather than
Cadmium (Cd) occurs naturally with zinc and lead in sulfide ores. Elevated concentrations in air, water, and soil may occur close to industrial emission sources, particularly those of nonferrous mining and metal refining industries.
