Copper electrorefining - Open Access .click

Chemical Engineering and Processing: Process Intensification, 2007
Abstract In copper electrorefining process, some additives are added to the electrolyte to improve the morphology of cathode deposits as well as the quality of products. In the present investigation, the effects of thiourea, glue and chloride ions (as additives) on the passivation of industrial copper anodes under high current densities have been ...

Processing of copper electrorefining anode slime: a review

Mineral Processing and Extractive Metallurgy, 2009
AbstractAnode 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 ...

Experimental method for direct electrorefining of both copper and copper alloy scrap

, 1998
The electrorefining of primary copper is a well known technology: in this work copper scrap was directly processed in the same way. The copper and copper alloy scrap was previously pressed by means of a 20 tons apparatus in order to avoid pyrometallurgical operations.
