ANODIC ELECTROLYTIC DISSOLUTION OF COPPER SULPHIDES PRECIPITATED FROM AMMONIACAL LEACHING MEDIA
(Sociedad Chilena de Química, 2009)
Electrochemical behaviour of copper electrode in concentrated sulfuric acid solutions
(Elsevier B.V., 1993-05-01)
The electrochemical behaviour of copper in 6.0 mol 1-1 sulfuric acid at 30°C, was studied by means of the potentiodynamic method. At low potential sweep rates, v < 200 m V s-1, the data reveal that the anodic process is ...
Copper Electrodeposition Kinetics Measured by Alternating Current Voltammetry and the Role of Ferrous Species
(Electrochemical Soc, 2016)
Impurities and additives play a key role in copper electrodeposition, in particular in upstream processes such as electrowinning or electrorefining. One common impurity is iron, mostly present as iron species Fe(II) in ...
High current-density anodic electro-dissolution in flow-injection systems for the determination of aluminium, copper and zinc in non-ferroalloys by flame atomic absorption spectrometry
(Taylor & Francis Ltd, 1999-01-01)
An automatic Procedure with a high current-density anodic electrodissolution unit (HDAE) is proposed for the determination of aluminium, copper and zinc in non-ferroalloys by flame atonic absorption spectrometry, based on ...

A lead-acid battery analogue to in situ anode degradation in copper electrometallurgy
(PERGAMON-ELSEVIER SCIENCE LTD, 1998)
When the applied current is interrupted in a copper electrowinning plant, lead anodes tend to corrode once the plant is back in operation. This work aims to show, both from theoretical considerations and experimental ...
