PROCESS FOR THE DESULPHURIZATION OF BLISTER COPPER |
摘要 |
The invention is concerned with an improved process for the desulphurization of blister copper during anode refining, wherein a mixture of an inert gas and an oxygen containing gas is blown into liquid blister copper. The improvement resides in varying the amount of oxygen containing gas in the mixture of nitrogen and oxygen during the desulphurization of blister copper. The process of the invention enables one to increase the recovery of copper, decrease the recycling of highly oxidized slag, decrease the time of desulphurization, decrease refractory wear, decrease subsequent time of reduction and decrease the amounts of reactants used. |
