Processing of copper electrorefining anode slime: a review
Institutions of Mining and Metallurgy Transactions Section C: Mineral Processing and Extractive Metallurgy, 2009AbstractAnode 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 ...

Mineralogical characterization of anode slimes: Part 10. Tellurium in raw anode slimes
Canadian Metallurgical Quarterly, 1996AbstractA mineralogical study of the raw anode slimes (that is, the slimes before decopperizing) from the refining of a typical commercial copper anode and three Te-rich copper anodes was carried out to elucidate the behaviour of tellurium in the refining circuit.

Mineralogical Characterization of Anode Slimes: Part 8—“Silica” in Copper Anodes and Anode Slimes
Canadian Metallurgical Quarterly, 1991Copper anodes from the CCR, Inco and Kidd Creek refineries contain ≍ 120 ppm SiO2. The silica is present as a variety of complex silicate inclusions preferentially located within 500 pm of the uppe...

Titrimetric determination of selenium in anodic slimes
Talanta, 1989The determination of selenium in the presence of tellurium and copper has been studied, to allow analysis of anodic slimes from electrolytic copper refining. Three methods have been developed for the determination of selenium in these slimes. They are based on the extraction of selenium with sodium sulphite, reduction of selenite with sodium sulphite ...

AbstractKupferglimmer, CU3Ni2−x SbO6−x where x = 0.1–0.2, occurs in copper anodes of the CCR Division of Nor and a Minerals Inc. that contain >0.30% Ni and > 200 ppm Sb. The associated anode slimes are also kupferglimmer-bearing. The kupferglimmer in the CCR circuit shows a significant substitution of Sn for Sb, and most of the kupferglimmer grains ...

AbstractKidd Creek raw anode slimes from the bottoms of the refining cells, that consist principally of PbSO4, Ag2Se, AgCuSe, CuSe, Cu3Se2, Cu2O, CuSO4.5H2O, Sn–Cu arsenate and Sb–Bi–As–Pb oxide, were leached in various lixiviants. Reaction with aerated H2SO4 solubilizes Cu2O and CUSO4 5H2O, and also extracts a significant amount of Cu from the copper ...

AbstractCopper anodes and anode slimes from the Chuquicamata Division of Codelco-Chile were examined mineralogically. The copper matrix of the anodes contains most of the Ag and much of the As and Sb in solid solution. Numerous inclusions are present at the copper grain boundaries, and these consist mostly of Cu2O although grains of Cu2O–Cu2Se and Cu2O–

Anode slimes treatment: The boliden experience
JOM, 2003There are numerous approaches to the treatment of both copper and lead anode slimes. Although the chemistry and metallurgy has been described and discussed by many authors, few, if any, have described the environmental impact of these activities. Dust and especially selenium emissions are a problem both in the internal working environment as well as in

AbstractThe raw anode slimes produced in Inco's Copper Cliff Copper Refinery have been characterized by a variety of mineralogical techniques. The anode slimes consist principally of euhedral NiO crystals, Ag-Cu selenides, PbSO4 and silicates as well as trace amounts of Pb-Cu-Bi oxide, Ag2Te and BaSO4. The slimes particles generally are agglomerated by

197Au Mössbauer study of copper refinery anode slimes
Metallurgical Transactions B, 1993Copper refinery anode slimes are abundantly produced during the electrolytic refining of copper. Although the slimes contain significant and economically recoverable amounts of gold and silver, the chemical state of the gold has not been fully identified.
