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, i.e. the electrode reactions are, at the anode: M → Mn+ + ne-and at the cathode: Mn+ + ne-→ M

Outotec® Anode Scrap Washing Machine. Carry out all material handling tasks for anode scrap automatically. The Outotec Anode Scrap Washing Machine will efficiently wash and pack scrap anodes in copper electrorefining plants for recycling. It uses closed washing water circulation for a clean, slime-free, and dry washing process.
The Outotec Precious Metals Plant is commonly used for treating copper anode slime for precious metals recovery and refining. It can also be used for other similar materials such as lead anode slime and other materials containing precious metals.
Copper cathode casting to oxygen-free copper rod. The most profitable part is from copper scrap to copper cathode. Energy consumption is: 100-120 m3 NG plus 35kwh per ton copper anode and 300Kwh per ton copper cathode. Single production line is flexible for engineering design, minimal capacity 1tpd and up to 60tpd.

are copper scrap, WEEE scrap of different qualities, especially printed circuit boards, dust, slag, lead production alloys containing precious metals, and anode slime from copper electrolysis. Depending on the purpose, different water-cooled lances are used for melting, oxidation, reduction, or flue dust feeding.
Maerz is a specialist for industrial furnace plants and one of the leading suppliers of engineering, know-how, and process technology to the steel and copper industry. ANDRITZ Maerz offers converter, melting and refining furnaces for primary and secondary copper production, as well as for the processing copper industry.
During the electrolysis process pure copper is deposited on cathode plates and impurities which are soluble fall to the bottom of the cell as anode slimes or sludge. Precious metals (Ag, Pt, Pd), can be extracted from the anode sludge created by the electro-refining process. Copper concentrates can also contain precious metals like gold and silver.
Anode slime is a byproduct from copper or lead electro-refining process. The copper/lead anode slime usually contain As, Sb, Bi and precious metals like gold and silver. Smelter of anode slime is most likely divided into two groups by the two different recovery processes based on its property and treatment capacity, i.e. pyrometallurgy and ...
Anode slime processing. The anode slimes from the Aurubis copper tankhouses are processed together with the rich lead from the lead refinery in the precious metal production plant. With Aurubis' modern, environmentally friendly precious metal production facilities, the company covers a wide range of feed materials rich in precious metals.
