Refining of blister copper

Refining of blister copper U. P. MULLICK IRUDE blister produced in smelting process may contain impurities like Fe, S, 0, Zn, Ni, As, Sb. The average compositions of blisters from primary and secondary raw materials are given in Table 1. SYNOPSIS The paper reviews the techniques of fire refining and electrolytic refining of blister copper

    REFINING OF BLISTER COPPER. Blister copper is refined by an electrolytic process. Blister copper in the form of a large plate is made as anode. A thin plate of pure copper is cathode. A solution of CuSO 4 is used as an electrolyte. The impure blister copper dissolves at the anode. During electrolysis pure copper is deposited in the form of pure

    The example results of continuous copper refining in laboratory scale at blister copper flowrate 5 kg/h in the form of oxygen content in oxidized copper and refined copper is shown in Figure 7. The obtained slag contained approximately 50% Cu, typical for refin-ing process. Oxygen content in reduced copper is about 1500 ppm, satisfying the condi

    Fire refining and electrolytic refining are used to purify blister copper even further. In fire refining, blister copper is usually mixed with flux and charged into the furnace, which is maintained at 1100 C (2010 F). Air is blown through the molten mixture to oxidize the copper and any remaining impurities. The impurities are removed as slag

    The fire refining is operated in either reverberatory or rotary furnaces known as anode furnaces. Through this step, oxygen and other impurities in the blister copper can be removed before the copper is cast into anode for electrolytic refining. The processed blister copper, also known as copper anode is cast into anode shapes
