USA Treatment of copper refinery anode slime ... A process for the removal of lead content in anode slime by subjecting the latter to primary and secondary leach in a medium of an ammonium acetate solution at a temperature not exceeding 80° C. Whereby lead dissolution is maximized and other metals are minimized.
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 electrorefining process. Copper concentrates can also contain precious metals like gold and silver.
A hydrometallurgical process is provided for the recovery of tellurium as elemental tellurium powder from copper refinery anode slime containing high amount of lead. The process involves the removal of copper and lead from anode slime followed by the recovery of tellurium as elemental powders. An economical and environment friendly process is provided for producing .
Selenium is obtained mainly as a byproduct of other metals, and is produced primarily from the anode mud of copper refineries. This paper presents a comprehensive review of selenium minerals, as well as the treatment of copper refinery anode slimes for the recovery of selenium.
Copper electrorefining (CuER) is the principal method for producing >70% of high or % pure copper cathodes from 9799% pure blister/fire refinedscrap copper anodes. While the inert and most of less soluble impurities settle as anode slime/sludge, other soluble impurities, particularly the metalloids (group VA/15 elements or Q: As, Sb and Bi) and some transition metals (Mt) codissolved ...
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.

The 333kg anodes containing % to % Cu are received, weighed and sampled, an important step: the anodes from Horne actually have more value in precious metals than in copper. The anodes are submerged in heated electrolyte solution in the tankhouse cells for 20 days, interspersed between cathode sheets; the application of a 23,000A ...
equipments for anode slime refinery. As a result of the electrorefining process the anode slime has been gained as ... is used, which is realized with the help of D8 Advance Bruker AXS equipment. ... Electrorefining of Copper.
Jul 18, 2013· 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 researchers to extract them .

of the silver Doré anodes being processed. The electrorefining process is continuous except when new silver Doré anodes are loaded in the cells and silver anode slime and anode scrap is discharged from the cells at the end of the electrolysis cycle. The anodes continuously dissolve, depositing refined silver on the cathodes.
the decoppered anode slime was washed several times, filtered and then dried at laboratory in the respective types of equipment. Samples of the dried anode slime are given in Fig. 4. XRD and XRF Anode Slime Analyses The characterization of the representative sample of anode slime composition was carried out by two
Jun 01, 1996· Effect of the KZC03 /anode slime ratio when roasting and further water leaching at room temperature, on the solubilization of Se. Conditions: roasting time = 6 h, leaching time = 30 min, 5 g of anode slime. When anode slimes are roasted at 400 only 50% Se is solubilized (Fig. 7), because the oxidation of selenides is incomplete.
Anode slime is one of the important secondary resources of copper, which is obtained as a byproduct during electrolytic refining of copper due to the settling of more noble metals such as gold ...
Nov 21, 2008· hi everybody.. i have read most of the topics in forum for 2 years but this is my first message.. i love recycling, especially precious metal winning. also i work in electrolithic copper plant. we produce lots of anode slimes every month that include ~2 kg/ton Au and ~ kg/ton Ag, %2540 Cu (Pb,Sn sulphates) Te,Se most of copper silver and gold in telluride and sellenide form.
