Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining.

Cadmium is a rare metal. The concentration of cadmium on the Earth is around 0.5 ppm (parts per million). Mostly it is present in the form of ores of zinc and sulfide. The sulfide ore of cadmium is termed as greenockite (CdS). Currently, cadmium is obtained from the mining, smelting and purification of ores of zinc sulfide, and copper sulfide.

Cadmium, a rare but widely dispersed element, is found naturally in the environment. Most cadmium ore (greenockite): occurs in association with zinc. It is released into the environment through mining and smelting, its use in various industrial processes, and enters the food chain from uptake by plants from contaminated soil or water.

The prime focus is on cadmium flows and cadmium emissions into the environment. ... The concentration of zinc in the recovered ore (called beneficiating) is done by crushing, grinding, and flotation processes (Fig. 1 ... Based on typical grade in Zn ore (40,000 ppm Zn, and 200 Cd), and current (June 27, 2003) prices of 0.78 $/lb for zinc, …
