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 ...

An investigation of copper and selenium recovery from copper anode slimes
International Journal of Mineral Processing, 2013Abstract In this study, an alternative method was investigated for the recovery of copper and selenium from copper anode slimes, supplied from Sarkuysan Co. in Turkey. The proposed process was composed of two hydrometallurgical steps; decopperization in H 2 SO 4 medium and dissolution of selenium into NaOH solution.

Processing of copper anodic-slimes for extraction of valuable metals
Waste Management, 2003This work focuses on processing of anodic slimes obtained from an Egyptian copper electrorefining plant. The anodic slimes are characterized by high concentrations of copper, lead, tin and silver. The proposed hydrometallurgical process consists of two leaching stages for the extraction of copper (H(2)SO(4)-O(2)) and silver (thiourea-Fe3+), and ...

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–

AbstractAnode copper from Inco's Copper Cliff Copper Refinery was characterized mineralogically to determine the composition, morphology and relative abundance of the phases present. The anode consists of a copper matrix containing numerous oxide and selenide inclusions, mostly present at the copper gram boundaries but also occurring within individual ...

Characteristics and Processing of Copper Refinery Anode Slime
2019The anode slime obtained from the copper electrorefining tank contains several valuable elements. The physico-chemical characteristics of the anode slime determines the processing route to recover these elements. The slime invariably contains Cu, Ni, Se, Te, Ag, Au & Platinum group metals (PGM).

Recovery of Silver and Gold from Copper Anode Slimes
JOM, 2014Copper anode slimes, produced from copper electrolytic refining, are important industrial by-products containing several valuable metals, particularly silver and gold. This article provides a comprehensive overview of the development of the extraction processes for recovering silver and gold from conventional copper anode slimes.

Recovery of Gold and Silver from Copper Anode Slime
Separation Science and Technology, 2000This study has shown that gold and silver can be recovered from a complex anode slime containing copper, selenium, and tellurium, but a carefully planned leaching procedure is required. To extract the gold with thiourea, it is necessary to first remove the copper, selenium, tellurium, and most of the silver from the mixture.

AbstractThe sulphation reactor slimes from Inco's Copper Cliff Copper Refinery have been characterized mineralogically to identify the phases present and to elucidate the reactions occurring. The slimes are agglomerated by a matrix phase which is rich in either silica gel or oxidate Se- Te-Ag compounds.

Anode slime behaviour in a laboratory‐scale copper electrorefining process
The Canadian Journal of Chemical Engineering, 1994AbstractCombining conventional electrochemical measurements, laser‐based visualization and digital image processing, the movement of anode slime, its spatial distribution and path of falling during the copper electrorefining process were investigated in a laboratory scale cell.
