The oxygen bottom blown copper smelting process is a newly developed intensifying smelting process, which has been widely applied to the copper productions in China in the past 10 years [6, 23].This process was industrially tested initially in the Shuikoushan (SKS) smelter in 1990 and was named originally as "SKS process ", …

The natural occurrence of elemental copper is a feature of its relatively low standard reduction potential of +0.158 volts, significantly below hydrogen in the electromotive series and hence relatively easily accumulated in elemental form as a consequence of normal geologic processes. This contrasts with the much more easily oxidized aluminum ...

AbstractCombining the knowledge of the phase relations with thermodynamic calculations, the basic problems in copper smelting are discussed on the Cu-Fe-S-O-SiO2 system in terms of sulphur-oxygen chemical potential diagrams. During the matte smelting stage, the variation in the activities of Fe3O4 and Cu2O is found to be small, even though the …

Abstract In the late 19th century, the discovery of rich nickel-copper sulphide ore bodies in Sudbury and the need for tonnage quantities of the metal to be used in nickel steel armour provided the foundation for establishing the Canadian nickel industry. For almost 50 years, International Nickel was the key player. In 1930, Falconbridge Nickel …

Early Smelting Practice. Virtually all the ore used by the ancients was handpicked with only the most worthwhile material being taken. Originally it was probably smelted by the Sumerians in shallow pits using charcoal as the fuel. How they first derived the necessary draught to raise the temperature sufficiently to melt the ore is still a ...

The smelting process can be divided into three stages, namely decomposition of high-valence sulphide, oxidation of sulphide, and matte smelting and slagging reaction (Fig. 1).The efficiency of matte smelting and matte-slag separation, as well as the extent of copper losses to slag are mainly affected by the oxidation/reduction potential, matte …
