The oxidation processes release so much thermal energy that temperatures of single particles may rise to >2000°C (Laurila et al., 2003), and even copper is vaporised to the gas stream.Some iron in larger particle fractions stays in sulphidic form during the suspension oxidation, due to ignition lower in the reaction shaft where most of oxygen …

The blister copper is then processed in an anode furnace to reduce its oxygen content. This increases the purity level to 98-99 per cent and the copper is then cast to form anodes. The anodes are placed in tanks with steel cathode plates. In the subsequent electrolytic refining process, copper migrates from anodes to cathodes, …

This is followed by a copper blow phase where the white metal is oxidised to blister copper. In this phase copper scrap is also added as coolant. Blister copper from PSCs is then fire refined to anode copper in Anode Furnaces (AF). Fire refining in AFs is another batch process including final oxi-a dation, reduction and anode castingsteps .

Coppermaking from sulfide concentrates entails two major steps: smelting and converting. In continuous direct-to-copper smelting process these two steps are combined into one. The principal advantages of this process are: isolation of SO2 emission to a single, continuous, SO2-rich gas stream, minimization of energy consumption and …

Converting the matte yields a high-grade "blister" copper, with 98.5 to 99.5 percent copper. Typically, blister copper is then fire-refined in an anode furnace, cast into "anodes", and sent to an electrolytic refinery for further impurity elimination. Roasting is performed in copper smelters prior to charging reverberatory furnaces. In roasting,
