CONTINUOUS FIRE REFINING OF BLISTER COPPER

CONTINUOUS FIRE REFINING OF BLISTER COPPER

The continuous fire refining of copper in a packed bed is a feasible process ensuring the proper copper oxidation, sulphur removal and copper reduction before anode casting. The dispersion and motion of a liquid copper in a ceramic packed bed increase the gas/ liquid reaction surface area resulting in a very high rate of oxidation and copper desul phurization. Similarly, dispersed copper in a ...

The final step consists of fire refining the blister copper to reduce the sulfur and oxygen to even lower levels. This oxidationreduction process is usually carried out in a separate furnace to ensure that the final smelter product reaches the level of percent copper that is required for electrolytic refining. At this point, the copper is cast into anodes, the shape and weight of which ...
