Cadmium - Assignment Point

Cadmium is found in nature in mineral forms and is obtained for commercial uses principally from cadmium ore, called greenockite, which is commonly found in association with zinc ore. Commercial production of cadmium ore depends on the mining of zinc. Some zinc ores concentrates from sulfidic zinc ores contain up to 1.4% of cadmium.
