Abstract
Thermal plasma technology may be useful for a broad range of applications in extractive and process metallurgy. Plasma technology is being used in the melting/remelting and refining of metals/alloys and scrap. Plasma technology may also be potentially useful in the benericiation of complex ores, treatment of wastes, reduction of oxides, the generation of value added products, and the recovery of precious metals from waste products. This paper gives an overview of thermal plasma applications in the field of extractive and process metallurgy.
