Pyrometallurgical Process an overview ScienceDirect Topics

One process evaporates cadmium in an open furnace, and cadmium is recovered as cadmium oxide powder. In the other process, cadmium is distilled, in a controlled furnace atmosphere, giving cadmium metal powder and a high-content nickel alloy. Pyrometallurgy can also use other reactive gases (than air) to obtain metal separation.
