Pyrometallurgy Metallurgy for Dummies

2021-1-19  Pyrometallurgy Basic Principle. The basic premise of most pyrometallurgical operations is simple: high-temperature chemistry is employed to segregate valuable metals in one phase while rejecting gangue and impurities in another phase. In most instances, both phases are molten (such as the matte and slag in a conventional copper smelting operation).

Oxygen Pyrometallurgy at Copper Cliff - TMS

This was demonstrated in Copper Cliff smelter full-scale tests on one of the seven 9.1 m X 33.5 m nickel reverberatory furnaces. These showed that one tonne of oxygen was equivalent to at least one half tonne of coal and that throughput rate could be increased 33% by a decrease in the nitrogen/oxygen ratio.

Abstract. Extraction of copper from sufidic ores, either by pyrometallurgy or hydrometallurgy, has various limitations. In this study, a solvometallurgical process for the extraction of copper from sulfidic ore minerals (chalcopyrite, bornite, chalcocite and digenite) was developed by using an organic lixiviant (FeCl 3 as oxidizing agent and ethylene glycol (EG) as organic solvent).
