Due to a fact that copper anodes at KUC contain a significant amount of bismuth. and control the bismuth contamination in the copper production. specifications for bismuth content in copper are 2. It also summarizes the contamination mechanism identified in the process control of copper electrorefining process at KUC.
The total direct plus indirect cost of producing electrorefined copper anode mud from the ore by conventional processes is in the range of 5 6 per kg of anode slime is profitable when the selling price is above the 5 6 per kg of cost data have been obtain from publish information and personal conduct in the copper industry.
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called cathodes, which will ultimately be made into products for everyday use.

Electrorefining of Copper. 1. Electrorefining – General Introduction In an electrorefining process, the anode is the impure metal and the impurities must be lost during the passage of the metal from the anode to the cathode during electrolysis, the electrode reactions are, at the anode: M → Mn+ + neand at the cathode: Mn+ + ne → M Electrorefining is a much more common process than electrowinning and .
10/13/2015 5 Fire Refining and Anode Casting • Virtually all the molten copper produced by smelting/converting is subsequently electrorefined. • Copper must be suitable for casting into thin, strong, smooth anodes for electrorefining cells. • This requires that the copper be firerefined to remove most of its sulfur and oxygen.

There are numerous viable approaches to the treatment of anode slimes from electrolytic copper refining. Of particular interest in the treatment of slimes are the behavior and recovery of selenium. The understanding of the process chemistry involved in the treatment of anode slimes should be aided considerably by recent work on the formation and characterization of slimes.
