CONTINUOUS FIRE REFINING OF BLISTER COPPER

2015-9-7  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.

FIRE REFINING OF BLISTER COPPER - OUTOTEC

Typically fire refining of blister copper is performed in two phases, oxidation phase and reduction phase. In oxidation phase air is blown to the blister copper and oxygen comprised in the air oxidizes sulfur to gaseous sulfur dioxide. Some of the oxygen also dissolves in the molten blister copper
