Copper electro-refining (Cu-ER) is the principal method for producing >70% of high or 99.97% pure copper cathodes from 97-99% pure blister/fire refined-scrap 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) co-dissolved ...
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 ...
The 333-kg anodes containing 99.1% to 99.4% 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 tank-house cells for 20 days, interspersed between cathode sheets; the application of a 23,000-A ...
equipments for anode slime refinery. As a result of the electro-refining 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.
Electrolysis process deposits pure copper (99.99%) on the stainless steel cathode plates. The impurities and precious metals contained in anodes settle down as anode slimes. Cathodes are then automatically washed, stripped and packed. The material handling equipment is sourced from Wenmec.
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.
Jan 01, 1990· KEYWORDS Tankhouse mechanization, anode scrap, anodes, cathodes, starting sheets, electrolyte, anode slimes. INTRODUCTION INCO's Copper Refinery which is located in Copper Cliff, Ontario, about two kilometers from the Smelter, was constructed in 1929-1930 by American Metals Company and INCO.
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.
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 .
The anode plates are approximately 1m x 1m x 0.05m in size, and weigh 380 kg per plate. 06 Refinery Anode plates and stainless steel cathode plates are alternately set into the electrorefining cell, where a proper level of DC current is supplied.

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
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.

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.
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.
