Jul 18, 2013· Abstract. Anode slime is the insoluble product deposited at the bottom of the electrorefining tank during electrorefining of copper. It generally contains Cu, Ni, Se, Te, Ag, Au, platinum group metals (PGM), Pb, Ba, Fe, etc. Owing to the presence of valuable metals and metalloids in the anode slime, numerous approaches have been made by the
Anode slime is one of the important secondary resources of copper, which is obtained as a by-product during electrolytic refining of copper due to the settling of more noble metals such as gold
PROCESSING OF COPPER ANODE-SLIMES FOR EXTRACTION OF METAL VALUES Received March 5, 2002, reviewed, accepted May 28, 2002 Processing of anodic slimes from an Egyptian copper electrorefining plant, exhibiting high contents of copper, lead, tin and silver has been presented. The proposed hydrometallurgical process
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 hydrometallurgy.
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.

Nov 01, 2020· Copper anode slimes usually consists of copper, selenium, nickel, tellurium, silver, gold, and trace amount of platinum group metals, with the Te content typically being about 1–4 wt%, and in some cases reaching as high as 8–9 wt% (Moats et al., 2007). For the copper anode slime processing, two main processes are operating in practice to recover valuable metals on industrial scale:

Amer studied processing of anode slime obtained from an Egyptian copper electrorefining plant [13]. The anode slime was characterized by high concentrations of copper, lead, tin and silver.
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.
from copper anode slime Recovery of gold from copper anode slimes is a multi-stages process There are more than 650 operating and planned copper mines, 140 smelters and 250 refineries world wide
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.

Nov 01, 2020· The raw material of copper telluride (Cu 2 Te) precipitate from anode slime processing used in the present study was obtained from Tongling Nonferrous Metals Smelter in China. It was dried at 120 °C for 24 h and then ground into fine particles with an average size of below 300 μm for further leaching experiments and analysis.
Copper telluride is a sort of solid waste generated from copper anode slime processing, from which the recovery of copper and particularly the high-value element of tellurium always encounter technical difficulties due to the complex physicochemical properties of tellurium.
Copper Anodes: In copper processing, a copper anode is an intermediate product from the smelting furnaces which is used as a copper source from which to make copper cathodes during electrolysis. In electrolysis, it is the positive terminal. Oxidation occurs at the anode. The anode is replaced when it’s been eroded too far and risk falling apart.
The anode slime is collected in the bottom of the electrolytic cells during the copper electrorefining. This slime generated during the copper refining process contains, among other base metals, costly precious metals. As previously mentioned, the blister copper, from the pyrometallurgical processing of copper sulphides (such as chalcopyrite

Anode slimes product is a by-product of the electro-refining process and consists of the insoluble impurities from the anode that fall to the bottom of the refining cell. The anode slimes are recovered from the refining cells, are dried in an oven and processed by a metals by-product plant.
To extract gold and silver from a copper anode slime with about 15% tin in a plant using the traditional pyrometallurgy-electrorefining technique, the recovery is only 90%. The rest of the gold and silver is lost in the slag which contains mainly SnO2, PbO, and Sb2O3 In the present work, a process is developed to recover the gold and silver further.
The invention relates to a hydrometallurgical metal for separating the precious metals and impurities of anode sludge obtained from copper electrolysis. According to the method, anode sludge copper is separated in atmospheric leaching; calcinated in two steps for separating selenium and for sulfatizing silver; the sulfatized silver is separated by leaching into a neutral aqueous solution, from
